Ensure that ALTER TABLE ONLY ENABLE/DISABLE TRIGGER does not recurse to child tables (lvaro Herrera), Fix handling of expressions in CREATE TABLE LIKE with inheritance (Tom Lane). In this blog we made a brief introduction to logical replication, a PostgreSQL feature introduced natively in version 10, and we have shown you how it can help you accomplish this challenge with a zero downtime strategy. If you are using an older version, such as version9.6, see Database Migration from Version 9 to 10. pg_upgrade uses this fact to perform rapid upgrades by creating new system tables and simply reusing the old user data files. Change the ps process display labels for background workers to match the pg_stat_activity.backend_type labels (Peter Eisentraut), Cause large object permission checks to happen during large object open, lo_open(), not when a read or write is attempted (Tom Lane, Michael Paquier). Previously, combinations of -U and a user name embedded in a URI caused incorrect reporting. How to subdivide triangles into four triangles with Geometry Nodes? pg_upgrade supports upgrades from 9.2.X and later to the current major release of PostgreSQL, including snapshot and beta releases. If you see anything in the documentation that is not correct, does not match Connect and share knowledge within a single location that is structured and easy to search. Add parenthesized options syntax to ANALYZE (Nathan Bossart). The release notes contain the significant changes in each PostgreSQL release, with major features and migration issues listed at the top. Changes. It will represent a valid uniqueness constraint across the whole partitioned table, even though each physical index only enforces uniqueness within its own partition. This supports creating extension modules that depend on other modules. If you used link mode and have Streaming Replication (see Section27.2.5) or Log-Shipping (see Section27.2) standby servers, you can follow these steps to quickly upgrade them. If you want to upgrade to the latest SUSE Managerversion, you must be using PostgreSQL version12 or13, depending on the underlying operating system: If you are running SLES 15 SP3, use PostgreSQL 13. If we have a load balancer like HAProxy, we can configure it using the PostgreSQL 10 as active and the PostgreSQL 11 as backup, in this way: So, if you just shutdown the master in PostgreSQL 10, the backup server, in this case in PostgreSQL 11, starts to receive the traffic in a transparent way for the user/application. The best answers are voted up and rise to the top, Not the answer you're looking for? This is similar to the syntax supported by VACUUM. E.4. The database schema and DDL commands are not replicated. Remove WITH clause in CREATE FUNCTION (Michael Paquier). PostgreSQL: Documentation: 15: pg_upgrade Prevent to_number() from consuming characters when the template separator does not match (Oliver Ford). Now, if there is ambiguity, the interpretation that matches the syntactic form is chosen. Specifically, the new variables are ERROR, SQLSTATE, ROW_COUNT, LAST_ERROR_MESSAGE, and LAST_ERROR_SQLSTATE. Ensure that standby servers will archive WAL timeline history files when archive_mode is set to always (Grigory Smolkin, Fujii Masao). If extension updates are available, pg_upgrade will report this and create a script that can be run later to update them. You will not be running pg_upgrade on the standby servers, but rather rsync on the primary. PostgreSQL: Documentation: 10: E.14. Release 10.10 the old PostgreSQL executable directory; environment variable PGBINOLD. Avoid misoptimization of subquery qualifications that reference apparently-constant grouping columns (Tom Lane). That's just cosmetic for our purposes, as we continue to select the fat mode in pre-v13 branches. The new command ALTER INDEX ATTACH PARTITION causes an existing index on a partition to be associated with a matching index template for its partitioned table. That is, the tables on the publication and on the subscription side must be normal tables, not views, materialized views, partition root tables, or foreign tables. This is performed by pg_replication_slot_advance(). Previously, CREATE DATABASE would be emitted without these specifications if the database locale and encoding matched the old cluster's defaults. (If you are faced with such an error from an existing index, REINDEX should be enough to fix it. PostgreSQL has long supported a more standard-compliant syntax for this capability. Prevent extensions from creating custom server parameters that take a quoted list of values (Tom Lane). When using link mode, standby servers can be quickly upgraded using rsync. I know. Link mode also requires that the old and new cluster data directories be in the same file system. Below is the complete archive of release notes for every version of PostgreSQL. E.10.2. Applications needing to check for a primary key should consult pg_index. (CVE-2020-25695), Fix usage of complex connection-string parameters in pg_dump, pg_restore, clusterdb, reindexdb, and vacuumdb (Tom Lane), The -d parameter of pg_dump and pg_restore, or the --maintenance-db parameter of the other programs mentioned, can be a connection string containing multiple connection parameters rather than just a database name. Per its versioning policy , the PostgreSQL community advises that users run the " latest available minor release available for a major version ." Copyright 1996-2023 The PostgreSQL Global Development Group, PostgreSQL 15.2, 14.7, 13.10, 12.14, and 11.19 Released. ESCAPE NULL and substring (text FROM pattern ESCAPE text) return NULL. This new TLS LDAP method for encrypted LDAP is enabled with ldapscheme=ldaps or ldapurl=ldaps://. L and TH now only consume characters that are not digits, positive/negative signs, decimal points, or commas. Ensure that pg_dump collects per-column information about extension configuration tables (Fabrzio de Royes Mello, Tom Lane). PostgreSQL 15.2, 14.7, 13.10, 12.14, and 11.19 Released, D.3. Perform a database backup. Allow VACUUM to avoid unnecessary index scans (Masahiko Sawada, Alexander Korotkov), Improve performance of committing multiple concurrent transactions (Amit Kapila), Reduce memory usage for queries using set-returning functions in their target lists (Andres Freund), Improve the speed of aggregate computations (Andres Freund), Allow postgres_fdw to push UPDATEs and DELETEs using joins to foreign servers (Etsuro Fujita). house for sale wedgewood ave riverview, nb; prestonwood country club wedding cost; can you use robinhood and webull at the same time As the schema is not replicated, you must take a backup in PostgreSQL 11 and restore it in your PostgreSQL 12. Allow postgres_fdw to push down aggregates to foreign tables that are partitions (Jeevan Chalke), Allow parallel building of a btree index (Peter Geoghegan, Rushabh Lathia, Heikki Linnakangas), Allow hash joins to be performed in parallel using a shared hash table (Thomas Munro), Allow UNION to run each SELECT in parallel if the individual SELECTs cannot be parallelized (Amit Khandekar, Robert Haas, Amul Sul), Allow partition scans to more efficiently use parallel workers (Amit Khandekar, Robert Haas, Amul Sul), Allow LIMIT to be passed to parallel workers (Robert Haas, Tom Lane). When x is a table name or composite column, PostgreSQL has traditionally considered the syntactic forms f(x) and x.f to be equivalent, allowing tricks such as writing a function and then using it as though it were a computed-on-demand column. If the partition key is part of the index's column set, a partitioned index may be declared UNIQUE. :-), List of deprecated features for PostgreSQL 8 to 13, When AI meets IP: Can artists sue AI imitators? This oversight could lead to failed to find parent tuple for heap-only tuple errors. The previous coding erroneously restricted all changes on such a role to superusers. Most server processes followed this practice already, but the archiver process was overlooked. Copyright 1996-2023 The PostgreSQL Global Development Group. This view will contain one row per subscription for the main worker (with null PID if the worker is not running), and additional rows for workers handling the initial data copy of the subscribed tables. Making statements based on opinion; back them up with references or personal experience. Build the new PostgreSQL source with configure flags that are compatible with the old cluster. It is based on a publish and subscribe mode, where one or more subscribers subscribe to one or more publications on a publisher node. Allow server options related to memory and file sizes to be specified in units of bytes (Beena Emerson). This also allows deferred unique constraints on partitioned tables. How to Upgrade PostgreSQL 11 to PostgreSQL 12 with Zero Downtime PostgreSQL stores data at /var/lib/pgsql/data/. Copy any custom full text search files (dictionary, synonym, thesaurus, stop words) from the old to the new cluster. (CVE-2020-25694), Prevent psql's \gset command from modifying specially-treated variables (Noah Misch). This cannot be supported at present because knowledge of the parameter's property would be required even before the extension is loaded. 1 - SIMILAR TO . Below you will find a detailed account of the changes between PostgreSQL 11 and the previous major release. Fix relation cache memory leaks with RLS policies (Tom Lane), Fix small memory leak when SIGHUP processing decides that a new GUC variable value cannot be applied without a restart (Tom Lane), Fix memory leaks in PL/pgsql's CALL processing (Pavel Stehule, Tom Lane), Make libpq support arbitrary-length lines in .pgpass files (Tom Lane). This provides flexibility in setting up a new partitioned index for an existing partitioned table. For Windows users, you must be logged into an administrative account, and then start a shell as the postgres user and set the proper path: and then run pg_upgrade with quoted directories, e.g. This new column more clearly distinguishes functions, procedures, aggregates, and window functions. I started with 9.1. Allow polygons to be indexed with SP-GiST (Nikita Glukhov, Alexander Korotkov), Allow SP-GiST to use lossy representation of leaf keys (Teodor Sigaev, Heikki Linnakangas, Alexander Korotkov, Nikita Glukhov), Improve selection of the most common values for statistics (Jeff Janes, Dean Rasheed). With these new versions 10 and 11, PostgreSQL implements built-in logical replication which, in contrast with physical replication, you can replicate between different major versions of PostgreSQL. This reduces memory usage for logical decoding. Major enhancements in PostgreSQL 11 include: Improvements to partitioning functionality, including: Add support for partitioning by a hash key, Add support for PRIMARY KEY, FOREIGN KEY, indexes, and triggers on partitioned tables, Allow creation of a default partition for storing data that does not match any of the remaining partitions, UPDATE statements that change a partition key column now cause affected rows to be moved to the appropriate partitions, Improve SELECT performance through enhanced partition elimination strategies during query planning and execution, CREATE INDEX can now use parallel processing while building a B-tree index, Parallelization is now possible in CREATE TABLE AS, CREATE MATERIALIZED VIEW, and certain queries using UNION, Parallelized hash joins and parallelized sequential scans now perform better, SQL stored procedures that support embedded transactions, Optional Just-in-Time (JIT) compilation for some SQL code, speeding evaluation of expressions, Window functions now support all framing options shown in the SQL:2011 standard, including RANGE distance PRECEDING/FOLLOWING, GROUPS mode, and frame exclusion options, Covering indexes can now be created, using the INCLUDE clause of CREATE INDEX, Many other useful performance improvements, including the ability to avoid a table rewrite for ALTER TABLE ADD COLUMN with a non-null column default. By default, pg_upgrade will wait for all files of the upgraded cluster to be written safely to disk. pg_upgrade requires the specification of the old and new cluster's data and executable (bin) directories.
