E.1. Postgres Pro Enterprise 16.8.2 #
Release Date: 2025-04-11
E.1.1. Overview #
This release is based on Postgres Pro Enterprise 16.8.1. As compared with Postgres Pro Enterprise 16.8.1, this version provides the following changes:
Fixed high CPU consumption on a standby instance with enabled cascading logical replication. Now wake-ups of walsender processes are sent after applying a group of WAL records rather than each individual record in case of high stream of changes from the upstream instance.
Fixed an issue when the checkpointer process could get stuck, repeatedly throwing “invalid memory alloc request size” errors. This could occur when using a huge
shared_bufferssetting, causing memory allocation requests to exceed the allowed limit.Fixed a segmentation fault, which could occur when using postgres_fdw with autonomous transactions.
Upgraded oracle_fdw to fix a crash with column options on non-existing columns. If the Oracle table has fewer columns than the Postgres Pro and one of these extra columns has a column option set, oracle_fdw would write past the end of an array, leading to memory corruption and crashes. Now options for such columns are ignored.
E.1.2. Migration to Version 16.8.2 #
If you are upgrading from a Postgres Pro Enterprise release based on the same PostgreSQL major version, it is enough to install the new version into your current installation directory.
To migrate from PostgreSQL, as well as Postgres Pro Standard or Postgres Pro Enterprise based on a previous PostgreSQL major version, see the migration instructions for version 16.
