This table outlines which features were added in which version. Version 10 has a number of backwards-incompatible changes which may affect system administration, particularly around monitoring and backup automation. help developers to build applications; help administrators to build fault-tolerant environment by protecting data integrity. We’ve covered this open source database in the past here on the blog. It’s still in beta stage but it has following exciting new features that I have been waiting for: Table partition. OmniDB debugger for PostgreSQL 11 November 6, 2018 / 0 Comments / in OmniDB, William's PlanetPostgreSQL / by William Ivanski.

Both have additional details on some of the features mentioned here, as well as others that may be of interest. Transition Tables. More than 160 new features have been added in PostgreSQL 13 compared to its previous versions. PostgreSQL development aims for conformance with the latest official version of the standard where such conformance does not contradict traditional features or common sense. However, I think it’s fair to say that this version can be still considered fresh for most users, and surely only a small percentage of users has upgraded. More than 160 new features have been added to PostgreSQL 11. The community strongly recommends that tools use either the GUC server_version_num (on the backend), or the libpq status function PQserverVersion in libpq to get the server version. Executor Speedups. While PostgreSQL 9.6 offers parallel query, this feature has been significantly improved in PostgreSQL 10, with new features like Parallel Bitmap Heap Scan, Parallel Index Scan, and others. Databases running on PostgreSQL version 7.4 and earlier will not be supported by 10's pg_dump or pg_dumpall. The corresponding B-tree indexes may also have many duplicated index entries. Remove pg_dump / pg_dumpall support for dumping from pre-8.0 servers (Tom Lane) If table columns are not unique, many identical values may exist. PostgreSQL 10 introduces scram authentication, specifically SCRAM-SHA-256, which is much more secure. Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. New Features & Enhancements CTE Enhancements Uses temporary replication slots by default, WAL streaming supported in tar mode (-Ft). PostgreSQL 10 added a ton of exciting new features which everyone should look at. See also Michael Paquier's blog on this topic. Improved Parallel Query : While PostgreSQL 9.6 offers parallel query, this feature has been significantly improved in PostgreSQL 10, with new features like Parallel Bitmap Heap Scan, Parallel Index Scan, and others. Those directories have been renamed to pg_wal and pg_xact, which we hope will be clearer. In PostgreSQL 10, merge joins can also be performed in the parallel portion of the plan. In PostgreSQL 10, it's possible to do list or range partitioning using dedicated syntax, and INSERT performance has been greatly improved. Wording from Magnus Hagander's new features presentation. The wait_event_type and wait_event columns added to the pg_stat_activity view in Postgres 9.6 give us a significant new window to find which parts of the system are causing query delays and gives us very accurate statistics on where we are losing performance. The new features in PostgreSQL 10 that increase database performance include: Improved Query Parallelism: Basic parallel query was introduced in PostgreSQL … This manual section explains the feature in more detail, and this section shows some examples. To get more information about a feature, click the link or hover the mouse pointer over the text. Improved Wait Events. The PostgreSQL Global Development Group today announced the release of PostgreSQL 13. Encoding conversions are now faster, and so is sorting. PostgreSQL 13 New Features. For example, we might decide to partition the `book_history` table, probably a good idea since that table is liable to accumulate data forever. This simplifies the logic at application level: there is no need for it to know exactly which node is the primary and which ones are the standbys. PostgreSQL 10 adds logical replication which is very easy to configure and which works at table granularity, clearly a huge step forward. That was terrible, so now it doesn't. This simplifies the logic at application level: there is no need for it to know exactly which node is the primary and which ones are the standbys. Outline • About Me • History: PostgreSQL前世今生 • PostgreSQL 10 新特性 • PostgreSQL Ecosystem • 台灣PostgreSQL使用者社群 2Taiwan PostgreSQL User Group2017/8/11 In previous versions of PostgreSQL, PostgreSQL supported only table inheritance, which could be used to simulate table partitioning, but it was complicated to set up and the performance characteristics were not that great. However, a good deal of other work has been done, including the necessary prerequisite step of revamping the bucket split algorithm to improve performance and concurrency, caching the metapage for better performance, adding page-at-a-time vacuuming, and expanding them more gradually. It looks like the Gist index for inet was known to be poor and someone worked on an SP-Gist index to try to improve the situation. You can compress the transaction log while streaming it. PostgreSQL 10 New Features 1. I’ve been involved in the PostgreSQL project since the 8.4 release cycle (2008-2009), and I’ve never seen anything like this. PostgreSQL 12 is the next major release of the world’s most popular and feature-rich open source database. Similarly, the word "location" in function names, where used to refer to transaction log location, has been replaced with "lsn". The first of these new capabilities have come with PostgreSQL 10. Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. Streaming replication is a fast, secure and is a perfect mechanism for high availability/disaster recovery needs. There were a lot of new features committed to the partitioning space in PostgreSQL 11. Parallel Index Scan and Index-Only Scan: It's now possible for the driving table to be scanned using an index-scan or an index-only scan. PostgreSQL 10 introduced declarative partitioning. Learning PostgreSQL 10 Book Description: PostgreSQL is one of the most popular open source databases in the world, and supports the most advanced features included in SQL standards and beyond. One of these features that makes life easier for administrators is related to additional information in pg_stat_activity. Smarter Connection Handling. This returns a six-digit integer version number which will be consistently sortable and comparable between versions 9.6 and 10. The stable version of PostgreSQL 12 is scheduled to be released in late 2019. As of Version 10, PostgreSQL no longer uses three-part version numbers, but is shifting to two-part version numbers. PostgreSQL 10.0 has many new features that can help the administrator reduce work and make systems more robust. Pass Query Text To Workers: The query text associated with a parallel worker will show up in pg_stat_activity. Many administrative functions have been renamed to use "wal" and "lsn": Some system views and functions have had attribute renames: Several command-line executables have had parameters renamed: PostgreSQL's original client/server protocol, version 1.0, will no longer be supported as of PostgreSQL 10. PostgreSQL 10 offers an exciting new set of features in addition to making further improvements to many of the already existing features including Big Data, Replication and Scaling, Administration, SQL, XML and JSON, Security, Performance and a lot more. However, there are quite a few other significant features as well which could easily have qualified as headline features in a release less jam-packed than this one. There have been many big features added to PostgreSQL 13, like Parallel Vacuum, de-duplication of indexes, etc., and a complete list can be found at PostgreSQL 13 release notes.Along with the big features, there are also small ones added, including dropdb –force. On most default installations the value for shared_buffers is way too low (in my opinion). The PostgreSQL community continues its consistent cadence of yearly major releases with PostgreSQL 12.

The PostgreSQL Global Development Group today announced the release of PostgreSQL 13. Client support is required in order to switch to SCRAM authentication in PostgreSQL. The PostgreSQL Global Development Group announces that the first beta release of PostgreSQL 12 is now available for download. Since it's a log table, we'll range partition it, with one partition per month. And now, PostgreSQL 11 has introduced the missing piece: hash partitioning. Here are some of them: Extended Statistics (ndistinct, functional dependencies). Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. PostgreSQL 13 New Features. Multivariate statistics objects can be used to let the planner learn about this, which proofs it against making such mistakes. Grouping sets now support hash aggregation. The list of new features coming in PostgreSQL 10 is extremely impressive. Durable Hash Indexes. If you're a developer adding write-ahead logging to a new storage form, or a user who thinks the developers may have introduced a bug, you'll be pleased to be able to test with wal_consistency_checking. pg_basebackup now has --wal-method rather than --xlog-method.

It supports both SQL for relational and JSON for non-relational queries. 2.1 Improve analytic query performance PostgreSQL 11 has been enhanced to improve the performance of long-running analytical queries. This involves converting the JSONB field to a `tsvector`, then creating an specific language full-text index on it: Once that's set up, you can do full-text searching against all of the values in your JSON documents: SCRAM is more secure than MD5 and has become the standard way to do authentication. PostgreSQL (/ ˈ p oʊ s t ɡ r ɛ s ˌ k juː ˈ ɛ l /), also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance.It was originally named POSTGRES, referring to its origins as a successor to the Ingres database developed at the University of California, Berkeley. In PostgreSQL 10, partition table feature uses a more sophisticated table distribution method.

As usual, PostgreSQL users should carefully test for the incompatibilities before upgrading in production. PostgreSQL 12 introduces features opening up new development opportunities while simplifying the management of some already robust capabilities, such as new ways to query JSON data, enhancements to indexes, and better performance with partitioned tables. Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. PostgreSQL 10 came up with declarative partitioning, using two of the three most common partitioning methods: list and range. It’s also useful for querying standbys. Users who have been continuously upgrading since before version 8.3 will need to either manually modify their databases to use the built-in tsearch objects before upgrading to PostgreSQL 10, or will need to compile tsearch2 themselves from scratch and install it. It is a salted challenge response authentication method. PostgreSQL 12 received significant performance improvements to the partitioning system, notably around how it can process tables that have thousands of partitions. Postgres 10 is allowing applications to define multiple connection points and define some properties that are expected from the backend server. In the latter approach, stealing the hashed password from the database or sniffing it on the wire is equivalent to stealing the password itself, even if you can't compute a preimage. A genuine identify column. To enhance the working potential of SQL Server 2016, new features ranging from security to querying abilities, Microsoft has incorporated R analytics, cloud integration and other technicalities. During execution this allows early skipping to the next outer row once a match is found. PostgreSQL has had logical decoding -- basically change capture -- since version 9.4, which has been embraced with enthusiasm, but it could not be used for replication without an add-on of some sort. My OpenProject management software is installed with default postgresql 10. [Disclaimers: (1) Other people may have different opinions. This automated translation should not be considered exact and only used to approximate the original English language content. While PostgreSQL 9.6 offers parallel query, this feature has been significantly improved in PostgreSQL 10, with new features like Parallel Bitmap Heap Scan, Parallel Index Scan, and others. PostgreSQL 10 came up with declarative partitioning, using two of the three most common partitioning methods: list and range. FDW Aggregate Pushdown. pg_create_logical_replication_slot: wal_position -> lsn, pg_create_physical_replication_slot: wal_position -> lsn, pg_logical_slot_get_changes: location -> lsn, pg_logical_slot_peek_changes: location -> lsn. It is one of the most popular databases supporting JSON (non-relational) queries and SQL for (relational) queries. PostgreSQL's functionality in that area is still fairly weak." As it works on the whole instance, replicating only part of the primary server is not possible, nor is it possible to write on the secondary. Particularly, since I'm not copying the patrons or books tables, I'll want to drop some foreign keys that they origin database has. PostgreSQL 10 it’s coming soon, so I will write some small posts about new features in this amazing release of the most advanced open source database. Since version 1.0 was superceded by version 2.0 in 1998, it is unlikely that any existing clients still use it. version 10 improves the synchronous_standby_names GUC by adding the FIRST and ANY keywords: FIRST was the previous behaviour, and the nodes priority is following the list order in order to get a quorum. In PostgreSQL 10, you'll be able to see latch waits and I/O waits, even for auxiliary processes and unconnected background workers. row that FOR EACH ROW triggers require.

More than 160 new features have been added to PostgreSQL 11. In this blog we’ll take a look at these new features and show you how to get and install this new PostgreSQL 12 … PostgreSQL 12 is now available with notable improvements to query performance (particularly over larger data sets and overall space utilization) among other important features.. So I was quite excited when PostgreSQL 10.0 was released in October 2017, bringing with it a slew of new features and enhancements. Real-world data frequently contains correlated data in table columns, which can easily fool the query planner into thinking WHERE clauses are more selective than they really are, which can cause some queries to become very slow. One of them is the ability to write SQL procedures that can perform full transaction management, enabling developers to create more advanced server-side applications. Before this feature, Improved Parallel Query. in postgresql.conf. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Let’s start mentioning some of the most important features and improvements of this new PostgreSQL version. The latest and greatest release of PostgreSQL, v11, is due out later this week! For the small number of users who are using this option a dump/restore will be required to upgrade to PostgreSQL 10. The most notable change is that changes to a hash index now write WAL, which means that they are crash-safe and that they are properly replicated to standbys. If you need to convert a database that old, use version 9.6 or earlier to upgrade it in two stages. The new features in PostgreSQL 10 that increase database performance include: Improved Query Parallelism: Basic parallel query was introduced in PostgreSQL 9.6, giving way to expanded capabilities for implementation of greater functionality for real world use cases. pgAdmin may be used on Linux, Unix, macOS and Windows to manage PostgreSQL and EDB Advanced Server 9.5 … True, some of those features still aren't as complex or sophisticated as you might find in commercial databases. Here are some typical new features and benefits. With extended statistics, you can tell the system to gather additional statistics according to parameters that you specify, which may help it get the plan right. Learning PostgreSQL 10 Book Description: PostgreSQL is one of the most popular open source databases in the world, and supports the most advanced features included in SQL standards and beyond. Now that MySQL 8 and PostgreSQL 10 are out, it's a good time to revisit how the two major open source relational databases compete against each other.. Before these versions, the general perception has been that while Postgres is superior in feature sets and its pedigree, MySQL is more battle tested at scale with massive concurrent reads/writes. Furthermore, at least on Red Hat, glibc regularly whacks around the behavior of OS-native collations in minor releases, which effectively corrupts PostgreSQL's indexes, since the index order might no longer match the (revised) collation order. To me, changing the behavior of a widely-used system call in a maintenance release seems about as friendly as locking a family of angry racoons in someone's car, but the glibc maintainers evidently don't agree. SCRAM-SHA-256. 3.1.1 For large amount data □ Native Partition Table Native Partition Table is provided as a method of physically partitioning a large scale table. You can set . This feature makes AFTER STATEMENT triggers both useful and performant by Starting with PostgreSQL 10, many new features have been added to PostgreSQL, which contribute greatly to the success of this exceptional open source product. make expression and targetlist projection faster, speed up queries that compute multiple aggregates, joins where one side can be proven unique, auxiliary processes and unconnected background workers, find you the server that is currently accepting write connections, interrogate the commit status of a transaction, compress the transaction log while streaming it, “PostgreSQL COPY FROM PROGRAM” is not a vulnerability, What 3000 Users Say About the PostgreSQL Tools They Use, Exploring Why PostgreSQL is Loved by Developers, 3 Keys to Finding Digital Transformation Success Using Open Source, 2020 Year-End Wrap Up Video: A Year of Postgres Growth. PostgreSQL 11 was released on October 10th, 2018, and on schedule, marking the 23rd anniversary of the increasingly popular open source database.. We’ve covered this open source database in the past here on the blog. PostgreSQL 11 made it much easier to use. Advanced partitioning features that were always on demand. Over the last few weeks, new versions of both PostgreSQL (version 10) and MariaDB (version 10.3.2) were released, which makes this an opportune time to compare the two and discuss new features … PostgreSQL 10 adds a new authentication option - SCRAM-SHA-256 - which is superior to MD5 and should be preferred. PostgreSQL 12 lets you really scale your partitions. enhancements and breaking changes in PostgreSQL 12. example: (from Magnus Hagander's new features presentation), Compile-time configuration option to use an ICU library instead of relying on OS-supplied internationalization library (which was prone to unexpected behavior), More robust collations with ICU support in PostgreSQL 10. XMLTABLE makes querying XML data faster and easier. Postgresql 10 new features. Postgresql 10 new features. The new parameter can also be controlled by environment variables. (wording from Bruce Momjian's general pg10 presentation). While all PostgreSQL releases typically contain at least some performance improvements, the rewrite of expression and targetlist projection is a particularly large and significant improvement which will benefit many users. Speedups of 2-4x are common with parallel query, and these enhancements should allow those speedups to happen for a wider variety of queries. Subplan-Related Improvements: A table with an uncorrelated subplan can appear in the parallel portion of the plan. I guess it only take one big bug for people to start worrying about their data and that is fair, but "buggy" is not a description I would use for the, in my experience, rock solid replication in PostgreSQL. libicu, on the other hand, says they care about this. A genuine identify column. Here are some typical new features and benefits. pg_resetxlog has been renamed to pg_resetwal. In current releases, PostgreSQL relies exclusively on the collations supplied by the operating system, but this sometimes causes problems: collation behavior often differs between operating systems, especially between Linux and Windows, and it isn't always easy to find a collation for one operating system whose behavior matches that of some collation available on another system. One point to note is that, unless you are using libpq, you will not be able to use this feature unless your particular client driver has been updated with SCRAM support, so it may be a while before this feature is universally available. Clients older than version 6.3 may be affected. Coupled with foreign tables pointing to external XML data, this can greatly simplify ETL processing. This article walks you through the summary of most important new features. 2ndQuadrant is the Gold Standard for PostgreSQL Products & Services and consistently contributes enterprise features to enhance performance, scalability, security, and stability in PostgreSQL. And now, PostgreSQL 11 has introduced the missing piece: hash partitioning. The next notable new feature introduced in PostgreSQL 10 is declarative table partitions. The easiest trick to let postgresql perform a lot better (apart from setting and using proper indexes of course) is just to give it more RAM to work with (if you have not done so already).
