E.2. Postgres Pro Enterprise 14.13.2
Release Date: 2024-10-24
E.2.1. Overview
This release is based on Postgres Pro Enterprise 14.13.1 and provides the following changes:
Introduced various optimizations in the implementation of improved performance for subsystems on top of SLRU, including more consistent use of
int64and acquiring the correct SLRU bank lock. The latter fixes an issue with zeroedpg_serialpages, which could manifest itself in “could not access status of transaction” errors.Fixed an issue to avoid potential stack overflow in scenarios involving a large number of subtransactions. Now when handling the process of committing a transaction, iteration is used instead of tail recursion.
Fixed an issue that caused a terminated CFS worker to respawn with a duplicate with the same worker ID. This led to multiple instances of the same worker competing for the recovery of compressed segments.
Fixed a race condition in committing serializable transactions.
Fixed an issue in
pg_serial, which could arise when the transaction counter reached values over 232.Fixed a memory leak in
walsenderin multimaster.
