Options. Perform a database backup. For example, the optimizer is improved in almost every release, but the improvements are usually observed by users as simply faster queries. Learn more about Stack Overflow the company, and our products. Allow access to file system functions to be controlled by GRANT/REVOKE permissions, rather than superuser checks (Stephen Frost). Previously, the 16MB default could only be changed at compile time. Prevent non-superusers from reindexing shared catalogs (Michael Paquier, Robert Haas). to report a documentation issue. The pgsql-committers email list records all source code changes as well. XML Limits and Conformance to SQL/XML. Columns can be included even if their data types don't have B-tree support. Block DECLARE CURSOR WITH HOLD and firing of deferred triggers within index expressions and materialized view queries (Noah Misch). Join for inspiration, news about database stuff, this, that and more. Make sure both database servers are stopped using, on Unix, e.g. My tip is not to spend too much time with this huge list, most of which you won't understand. E.10. Release 11.10 - PostgreSQL Documentation However, if both interpretations are feasible, the column interpretation was always chosen, leading to surprising results if the user intended the function interpretation. : or on Windows, using the proper service names: Streaming replication and log-shipping standby servers can remain running until a later step. The file names still use an sgml extension for compatibility with back branches. The changes on the publisher are sent to the subscriber as they occur in real-time. PostgreSQL only allows superusers to access postgres_fdw tables without passwords, e.g., via peer. This oversight could lead to failure of subsequent PITR recovery attempts. ), Handle concurrent desummarization correctly during BRIN index scans (Alexander Lakhin, lvaro Herrera). Show memory usage in output from log_statement_stats, log_parser_stats, log_planner_stats, and log_executor_stats (Justin Pryzby, Peter Eisentraut), Add column pg_stat_activity.backend_type to show the type of a background worker (Peter Eisentraut), Make log_autovacuum_min_duration log skipped tables that are concurrently being dropped (Nathan Bossart), Add information_schema columns related to table constraints and triggers (Peter Eisentraut). Previously returned true, if ESCAPE NULL is specified. pg_dump and pg_restore, without --create, no longer dump/restore database-level comments and security labels; those are now treated as properties of the database. You have to read through all of these sections for all of the base releases between 8.x and 13. Compression is already disabled in modern OpenSSL versions, so that the libpq setting had no effect with such libraries. 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). This is performed by pg_replication_slot_advance(). Heavy use of parallel processing has been observed to cause postmaster crashes due to too many concurrent signals requesting creation of a parallel worker process. Allow partition elimination during query execution (David Rowley, Beena Emerson). As the schema is not replicated, we must take a backup in PostgreSQL 10 and restore it in our PostgreSQL 11. postgres 9 to 12 breaking changespublic adjusters are crooks. How to Upgrade PostgreSQL10 to PostgreSQL11 With Zero Downtime Eliminating OIDs while upgrading PostgreSQL from 9.4 to 12, PostgreSQL 9.6.12 autovacuum constantly running on system tables, MySQL 8 - user variables within expressions is deprecated [UDF calls with lot of parameters]. Allow server options related to memory and file sizes to be specified in units of bytes (Beena Emerson). Is there such a thing as aspiration harmony? Allow parallelization of commands CREATE TABLE AS, SELECT INTO, and CREATE MATERIALIZED VIEW (Haribabu Kommi), Improve performance of sequential scans with many parallel workers (David Rowley), Add reporting of parallel workers' sort activity in EXPLAIN (Robert Haas, Tom Lane), Allow B-tree indexes to include columns that are not part of the search key or unique constraint, but are available to be read by index-only scans (Anastasia Lubennikova, Alexander Korotkov, Teodor Sigaev). This reduces memory usage for logical decoding. Allow initdb to set group read access to the data directory (David Steele). The compile-time option ALLOW_DANGEROUS_LO_FUNCTIONS has been removed. For security, be sure that that directory is not readable or writable by any other users. It might also be necessary to adjust other configuration files in the new cluster to match the old cluster, e.g., postgresql.conf (and any files included by it), postgresql.auto.conf. Fix to_date(), to_number(), and to_timestamp() to skip a character for each template character (Tom Lane). PostgreSQL 14. Previously, such circumstances generated errors. This oversight could lead to failed to find parent tuple for heap-only tuple errors. your experience with the particular feature or requires further clarification, 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. The data in serial or identity columns backed by sequences will be replicated as part of the table, but the sequence itself would still show the start value on the subscriber. Previously, only superusers could call adminpack functions; now role permissions are checked. It is based on a publish and subscribe mode, where one or more subscribers subscribe to one or more publications on a publisher node. A dump/restore is not required for those running 11.X. Reduce the number of files copied by pg_rewind (Michael Paquier), Prevent pg_rewind from running as root (Michael Paquier), Add pg_dumpall option --encoding to control output encoding (Michael Paquier), Add pg_dump option --load-via-partition-root to force loading of data into the partition's root table, rather than the original partition (Rushabh Lathia). The subscription apply process will run in the local database with the privileges of a superuser. Speed up construction of query results (Andres Freund), Improve speed of access to system caches (Andres Freund), Add a generational memory allocator which is optimized for serial allocation/deallocation (Tomas Vondra). Most server processes followed this practice already, but the archiver process was overlooked. The query ID can now potentially display as a negative value. Sync our copy of the timezone library with IANA tzcode release 2020d (Tom Lane). This is mostly useful to allow using very long security tokens as passwords. The release notes do not contain changes that affect only a few users or changes that are internal and therefore not user-visible. This will work correctly if all affected tables are part of the same subscription. But there is no tool that will show you those things. PostgreSQL 9.5. A subscription is the downstream side of logical replication. Specifically, SELECT to_number('1234', '9,999') used to return 134. They want a report to estimate times. PostgreSQL: Documentation: 15: Appendix E. Release Notes Ensure that pg_dump collects per-column information about extension configuration tables (Fabrzio de Royes Mello, Tom Lane). (--checksum is necessary because rsync only has file modification-time granularity of one second.) Allow foreign keys on partitioned tables (lvaro Herrera), Allow FOR EACH ROW triggers on partitioned tables (lvaro Herrera). Replication is only possible from base tables to base tables. how long can you live with a coiled aneurysm? Observe the following incompatibilities: Make pg_dump dump the properties of a database, not just its contents (Haribabu Kommi). If you are going to be using link or clone mode, you should use the option --link or --clone with --check to enable mode-specific checks. Also add a check that the WAL timeline matches the backup_label file's timeline. Allow aggregate functions on partitioned tables to be evaluated separately for each partition, subsequently merging the results (Jeevan Chalke, Ashutosh Bapat, Robert Haas). I've been looking for a tool similar to "DMA", specifically the part that lists deprecated features and "breaking changes". Many prebuilt installers do this step automatically. Failure to do this led to crashes when specifying --inserts, or underspecified (though usually correct) COPY commands when using COPY to reload the tables' data. The data is then continuously transferred using the streaming replication protocol to the apply worker, which maps the data to local tables and applies the individual changes as they are received, in a correct transactional order. This can result in near-instantaneous copying of the data files, giving the speed advantages of -k/--link while leaving the old cluster untouched. This is useful for KNN-GiST searches when looking for coordinates in descending order. UPDATE statements that change a partition key column now cause affected rows to be moved to the appropriate partitions (Amit Khandekar), Allow INSERT, UPDATE, and COPY on partitioned tables to properly route rows to foreign partitions (Etsuro Fujita, Amit Langote). Previously, option names in certain SQL commands were forcibly lower-cased even if entered with double quotes; thus for example "FillFactor" would be accepted as an index storage option, though properly its name is lower-case. pg_upgrade creates various working files, such as schema dumps, stored within pg_upgrade_output.d in the directory of the new cluster. Also allow PL/Perl, PL/Python, and PL/Tcl to handle composite-domain function arguments and results. Start the upgrade. Clone mode provides the same speed and disk space advantages but does not cause the old cluster to be unusable once the new cluster is started. Save any configuration files from the old standbys' configuration directories you need to keep, e.g., postgresql.conf (and any files included by it), postgresql.auto.conf, pg_hba.conf, because these will be overwritten or removed in the next step. options to be passed directly to the old postgres command; multiple option invocations are appended, options to be passed directly to the new postgres command; multiple option invocations are appended, the old cluster port number; environment variable PGPORTOLD, the new cluster port number; environment variable PGPORTNEW, retain SQL and log files even after successful completion, directory to use for postmaster sockets during upgrade; default is current working directory; environment variable PGSOCKETDIR, cluster's install user name; environment variable PGUSER. Release date: 2020-11-12. This, of course, opens a new door for upgrading strategies. Use GRANT/REVOKE to control access to lo_import() and lo_export() (Michael Paquier, Tom Lane). Avoid running atexit handlers when exiting due to SIGQUIT (Kyotaro Horiguchi, Tom Lane). This allows free space to be reused more quickly. Allow single-evaluation queries, e.g., WHERE clause aggregate queries, and functions in the target list to be parallelized (Amit Kapila, Robert Haas), Add server parameter parallel_leader_participation to control whether the leader also executes subplans (Thomas Munro). pg_upgrade upgrade a PostgreSQL server instance, pg_upgrade -b oldbindir [-B newbindir] -d oldconfigdir -D newconfigdir [option]. Changes. The initial schema can be copied using pg_dump schema-only. Fix failure of parallel B-tree index scans when the index condition is unsatisfiable (James Hunter), Ensure that data is detoasted before being inserted into a BRIN index (Tomas Vondra), Index entries are not supposed to contain out-of-line TOAST pointers, but BRIN didn't get that memo.
