postgres 10 to 11 breaking changes

pg_upgrade is included in a default installation. 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). your experience with the particular feature or requires further clarification, The new server can now be safely started, and then any rsync'ed standby servers. This feature is disabled by default but can be enabled by changing enable_partitionwise_join. Fully enforce uniqueness of table and domain constraint names (Tom Lane). What positional accuracy (ie, arc seconds) is necessary to view Saturn, Uranus, beyond? If you see anything in the documentation that is not correct, does not match \gset without a prefix would overwrite whatever variables the server told it to. This cannot be supported at present because knowledge of the parameter's property would be required even before the extension is loaded. Generally, this option is useful for testing but should not be used on a production installation. ), Handle concurrent desummarization correctly during BRIN index scans (Alexander Lakhin, lvaro Herrera). E.20. Release 11 - PostgreSQL Documentation Also, arrange for the combination of a negative year and an explicit BC marker to cancel out and produce AD. This is accomplished with the new initdb option --allow-group-access. Migration to Version 11.10. This is useful if the system to be loaded to has different collation definitions or endianness, possibly requiring rows to be stored in different partitions than previously. Is there such a thing as aspiration harmony? There is also a web interface that shows changes to specific files. This is where the incompatibilities to the previous release are enumerated. pg_upgrade accepts the following command-line arguments: the old PostgreSQL executable directory; environment variable PGBINOLD, the new PostgreSQL executable directory; default is the directory where pg_upgrade resides; environment variable PGBINNEW, check clusters only, don't change any data, the old database cluster configuration directory; environment variable PGDATAOLD, the new database cluster configuration directory; environment variable PGDATANEW, number of simultaneous processes or threads to use, use hard links instead of copying files to the new cluster. XML Limits and Conformance to SQL/XML. this form If extension updates are available, pg_upgrade will report this and create a script that can be run later to update them. Below you will find a detailed account of the changes between PostgreSQL 11 and the previous major release. PostgreSQL 14 Breaks the .NET and Java Drivers for PostgreSQL - InfoQ Allow psql to test for the existence of a variable (Fabien Coelho). Remove WITH clause in CREATE FUNCTION (Michael Paquier). 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. There is no workaround for that, other than storing data in normal tables. Compression is already disabled in modern OpenSSL versions, so that the libpq setting had no effect with such libraries. Make sure the new binaries and support files are installed on all standby servers. For more information on backing up, see Backup and Restore. This documentation is for an unsupported version of PostgreSQL. The release notes contain the significant changes in each PostgreSQL release, with major features and migration issues listed at the top. 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 catalog contains the state for each replicated relation in each subscription. Ensure that psql reports the proper user name when prompting for a password (Tom Lane). how long can you live with a coiled aneurysm? The graphical installers all use version-specific installation directories. For example, the optimizer is improved in almost every release, but the improvements are usually observed by users as simply faster queries. Improve logging of LDAP errors (Thomas Munro), Add default roles that enable file system access (Stephen Frost). This rare problem would manifest in later apparent wraparound or could not access status of transaction errors. On May 12, 2022, the PostgreSQL Global Development Group released its regular quarterly update for all of its supported versions (10-14) containing bug fixes and a security fix for CVE-2022-1552. And now, we only need to change our endpoint from our application or load balancer (if we have one) to the new PostgreSQL 11 server. If you want to use link mode and you do not want your old cluster to be modified when the new cluster is started, consider using the clone mode. In PostgreSQL 11: $ psql -d postgres -f schema.sql. This extension is no longer considered to be a usable security tool or example of how to write an extension. Sync our copy of the timezone library with IANA tzcode release 2020d (Tom Lane). The release notes contain the significant changes in each PostgreSQL release, with major features and migration issues listed at the top. risk of data lose when a backup does not exist or cannot be replayed. Add storage parameter toast_tuple_target to control the minimum tuple length before TOAST storage will be considered (Simon Riggs). power(float8, float8) followed the standard if the C library does; but on some old Unix platforms the library doesn't, and there were also problems on some versions of Windows. Also, PL/Perl and PL/Python now install their include files, to support creation of transform modules for those languages. pg_upgrade_output.d and its contained files will be removed automatically if pg_upgrade completes successfully; but in the event of trouble, the files there may provide useful debugging information. Add timeline information to the backup_label file (Michael Paquier). This new column more clearly distinguishes functions, procedures, aggregates, and window functions. This is similar to using var LIKE 'word%' with a btree index, but it is more efficient. Several existing contrib modules that define data types have been adjusted to install relevant files. Because of the way PostgreSQL implements replication. 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). Replacement sorts were determined to be no longer useful. Columns can be included even if their data types don't have B-tree support. Disallow DROP INDEX CONCURRENTLY on a partitioned table (lvaro Herrera, Michael Paquier). Backends that were still waiting for a client startup packet got it wrong, too. It is important that any external modules are also binary compatible, though this cannot be checked by pg_upgrade. Avoid recursive consumption of stack space while processing signals in the postmaster (Tom Lane). Allow the creation of arrays of domains (Tom Lane). 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). Build the new PostgreSQL source with configure flags that are compatible with the old cluster. PostgreSQL: Documentation: 15: pg_upgrade to report a documentation issue. 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). Learn more about Stack Overflow the company, and our products. 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. This is enabled by the new INCLUDE clause of CREATE INDEX. The user creating a subscription must be a superuser. Prevent non-superusers from reindexing shared catalogs (Michael Paquier, Robert Haas). Correct information schema column tables.table_type to return FOREIGN instead of FOREIGN TABLE (Peter Eisentraut). This speeds access to partitioned tables with many partitions. 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. your experience with the particular feature or requires further clarification, Prevent logical replication workers from sending redundant ping requests (Tom Lane), During smart shutdown, don't terminate background processes until all client (foreground) sessions are done (Tom Lane). The compile-time option ALLOW_DANGEROUS_LO_FUNCTIONS has been removed. Server E.20.3.1.1. While rsync must be run on the primary for at least one standby, it is possible to run rsync on an upgraded standby to upgrade other standbys, as long as the upgraded standby has not been started. talladega high school basketball. In cases where these programs need to initiate additional connections, such as parallel processing or processing of multiple databases, the connection string was forgotten and just the basic connection parameters (database name, host, port, and username) were used for the additional connections. The above will start the replication process, which synchronizes the initial table contents of the tables in the publication and then starts replicating incremental changes to those tables. This absorbs upstream's change of zic's default output option from fat to slim. The initial schema can be copied using pg_dump schema-only. Previously returned true, if ESCAPE NULL is specified. The pgsql-committers email list records all source code changes as well. Also, writing FUNCTION is now preferred over writing PROCEDURE in CREATE OPERATOR and CREATE TRIGGER, because the referenced object must be a function not a procedure. This generates a C continue statement, causing a return to the top of the contained loop when the specified condition occurs. (Tablespaces and pg_wal can be on different file systems.) As side note: are you aware that before Postgres 10, the version numbering was a bit different? This is controlled by the huge_pages configuration parameter. Add prefix-match operator text ^@ text, which is supported by SP-GiST (Ildus Kurbangaliev). E.10.2. That's just cosmetic for our purposes, as we continue to select the fat mode in pre-v13 branches. 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. Also add ssl_passphrase_command_supports_reload to specify whether the SSL configuration should be reloaded and ssl_passphrase_command called during a server configuration reload. Here is a link to this for version 12. There is also a web interface that shows changes to specific files. Reduce var = var to var IS NOT NULL where equivalent (Tom Lane). If you see anything in the documentation that is not correct, does not match pg_upgrade (formerly called pg_migrator) allows data stored in PostgreSQL data files to be upgraded to a later PostgreSQL major version without the data dump/restore typically required for major version upgrades, e.g., from 9.5.8 to 9.6.4 or from 10.7 to 11.2. Allow bitmap scans to perform index-only scans when possible (Alexander Kuzmenkov), Update the free space map during VACUUM (Claudio Freire). Unfortunately, rsync needlessly copies files associated with temporary and unlogged tables because these files don't normally exist on standby servers. If the partition key is part of the index's column set, a partitioned index may be declared UNIQUE. Files that were not linked on the primary are copied from the primary to the standby. Worse, the connection might succeed but not be encrypted as intended, or be vulnerable to man-in-the-middle attacks that the intended connection parameters would have prevented. Sure, that's a lot of changes, but that's to be expected for such a jump. These parameters will be useful if we want to add a new replication slave or for using PITR backups. Install the new PostgreSQL binaries on standby servers.
