Bug Fixes and Improvements

This update fixes over 80 bugs that were reported in the last several months. \ 
The issues listed below affect PostgreSQL 15. Some of these issues may also \ 
affect other supported versions of PostgreSQL.

Included in this release:

Several fixes for CREATE DATABASE when using the STRATEGY = WAL_LOG, including a \ 
potential corruption that could lose modifications to a template/source \ 
database.
Fix crash with CREATE SCHEMA AUTHORIZATION.
Several fixes for MERGE.
Several fixes for triggers in partitioned tables.
Disallow altering composite types that are stored in indexes.
Ensure that COPY TO from a parent table with row-level security enabled does not \ 
copy any rows from child tables.
Adjust text-search-related character classification logic to correctly detect \ 
whether the prevailing locale is C when the default collation of a database uses \ 
the ICU provider.
Re-allow exponential notation in ISO-8601 interval fields.
Improve error reporting for various invalid JSON string literals.
Fix data corruption due to vacuum_defer_cleanup_age being larger than the \ 
current 64-bit xid.
Several fixes for the query parser and planner, including better detection of \ 
improperly-nested aggregates.
Fix partition pruning bug with the boolean IS NOT TRUE and IS NOT FALSE \ 
conditions. Prior to this, NULL partitions were accidentally pruned.
Fix memory leak in memoize plan execution.
Fix buffer refcount leak on foreign tables using partitions when performing \ 
batched inserts.
Restore support for sub-millisecond vacuum_cost_delay settings.
Several fixes for views and rules.
Avoid unnecessary work while scanning a multi-column BRIN index with multiple \ 
scan keys.
Ignore dropped columns and generated columns during logical replication of an \ 
UPDATE or DELETE action.
Several fixes for naming and availability of wait events.
Support RSA-PSS certificates with SCRAM-SHA-256 channel binding. This feature \ 
requires building with OpenSSL 1.1.1 or newer.
Avoid race condition with process ID tracking on Windows.
Fix memory leak within a session for PL/pgSQL DO blocks that use cast expressions.
Tighten array dimensionality checks from PL/Perl and PL/Python when converting \ 
list structures to multi-dimensional SQL arrays.
Fix pg_dump so that partitioned tables that are hash-partitioned on an \ 
enumerated type column can be restored successfully.
Fix for pg_trgm where an unsatisfiable regular expression could lead to a crash \ 
when using a GiST or GIN index.
Limit memory usage of pg_get_wal_records_info() in pg_walinspect.
