Date: 2026-04-03
E.1.1. Overview #
This release is based on Postgres Pro Enterprise 17.9.1 and provides the following changes:
Fixed an issue that could cause operations attempting to evict a buffer from the
temp_bufferscache to fail with the “block N of table_name is still referenced” message.Fixed an issue that allowed memory allocation in a critical section, which could cause errors to be reported with
PANICseverity level instead ofERROR.Implemented the ability to cache file descriptors for directories in
PGDATAand updated theopenandstatsystem calls to use these cached descriptors to reduce CPU usage when planning SQL queries.
E.1.2. Migration to Version 17.9.2 #
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 17.
