E.1. Postgres Pro Enterprise 12.20.2
Release date: 2024-10-23
E.1.1. Overview
This release is based on Postgres Pro Enterprise 12.20.1 and provides the following changes:
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.
E.1.2. Migration to Version 12.20.2
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 12.
