E.19. Postgres Pro Enterprise 13.2.2
Release Date: 2021-05-21
E.19.1. Overview
This release is based on Postgres Pro Enterprise 13.2.1 and provides the following change:
Fixed a bug in the CFS causing an incorrect assumption that the
pglzalgorithm is always used for data compression in CFS tablespaces regardless of the actually used one. This could cause “invalid page in block N of relation XXX” errors after migrating a cluster with CFS tablespaces from the previous Postgres Pro Enterprise version using pg_upgrade. To fix this issue, you can just install the current Postgres Pro Enterprise release.
E.19.2. Migration to Version 13.2.2
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.
If you have an installation of Postgres Pro Enterprise 13.2.1 that contains compressed tablespaces created without explicitly specifying the pglz algorithm, perform an upgrade as follows. Before upgrading, make a complete dump using pg_dumpall. Upgrade Postgres Pro Enterprise, re-create your database cluster, and restore the dump. Then you can create compressed tablespaces in the same way as before.
If you have already upgraded your installation with CFS tablespaces from Postgres Pro Enterprise 13.2.1, and you cannot access the compressed data, call the support team.
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 13.
