postgres 10 to 11 breaking changes

Avoid recursive consumption of stack space while processing signals in the postmaster (Tom Lane). How to Upgrade PostgreSQL10 to PostgreSQL11 With Zero Downtime pg_upgrade uses this fact to perform rapid upgrades by creating new system tables and simply reusing the old user data files. Specifically, allow RANGE mode to use PRECEDING and FOLLOWING to select rows having grouping values within plus or minus the specified offset. 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. PostgreSQL 13. Replication is only possible from base tables to base tables. Temporary Unix socket files for communication with these postmasters are, by default, made in the current working directory. This catalog contains information about all publications created in the database. How to Upgrade PostgreSQL 11 to PostgreSQL 12 with Zero Downtime In order to be able to copy the initial data, the role used for the replication connection must have the SELECT privilege on a published table. your experience with the particular feature or requires further clarification, Allow initdb to set group read access to the data directory (David Steele). 1 - SIMILAR TO . Generally, this option is useful for testing but should not be used on a production installation. Allow the server to specify more complex LDAP specifications in search+bind mode (Thomas Munro). You have to read through all of these sections for all of the base releases between 8.x and 13. Previously, the 16MB default could only be changed at compile time. Many prebuilt installers do this step automatically. Honor the capitalization of double-quoted command options (Daniel Gustafsson). My Blog. If you are using PostgreSQL10 or 12, you can upgrade to PostgreSQL13. pg_dumpall's output script will now always create databases with their original locale and encoding, and hence will fail if the locale or encoding name is unknown to the destination system. The old directory is renamed to /var/lib/pgsql/data-pg12 or /var/lib/pgsql/data-pg10, depending on the version you started from. 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. Ensure that standby servers will archive WAL timeline history files when archive_mode is set to always (Grigory Smolkin, Fujii Masao). (This is not supported on Windows.). Add the ability to define PL/pgSQL composite-type variables as not null, constant, or with initial values (Tom Lane), Allow PL/pgSQL to handle changes to composite types (e.g., record, row) that happen between the first and later function executions in the same session (Tom Lane).

How do the interferometers on the drag-free satellite LISA receive power without altering their geodesic trajectory? Copyright 1996-2023 The PostgreSQL Global Development Group, PostgreSQL 15.2, 14.7, 13.10, 12.14, and 11.19 Released, D.3. This extension is no longer considered to be a usable security tool or example of how to write an extension. : or on Windows, using the proper service names: Streaming replication and log-shipping standby servers can remain running until a later step. Previously, WAL was retained for two checkpoints. However, if a fast upgrade fails, you must restore the database from the backup. Specifically, the new roles are: pg_read_server_files, pg_write_server_files, and pg_execute_server_program. However, if both interpretations are feasible, the column interpretation was always chosen, leading to surprising results if the user intended the function interpretation. You can also specify user and port values, and whether you want the data files linked or cloned instead of the default copy behavior. This oversight could lead to failure of subsequent PITR recovery attempts. Add parenthesized options syntax to ANALYZE (Nathan Bossart). If the --link option was used, the data files might be shared between the old and new cluster: If pg_upgrade aborted before linking started, the old cluster was unmodified; it can be restarted. Again, use compatible initdb flags that match the old cluster. Copyright 1996-2023 The PostgreSQL Global Development Group, PostgreSQL 15.2, 14.7, 13.10, 12.14, and 11.19 Released. Most server processes followed this practice already, but the archiver process was overlooked.
