E.1. Postgres Pro 9.5.20.1
Release date: 2019-11-25
E.1.1. Overview
This release is based onPostgreSQL 9.5.20 andPostgres Pro Standard 9.5.19.2. All improvements inherited fromPostgreSQL 9.5.20 are listed inPostgreSQL 9.5.20 Release Notes.
As compared toPostgres Pro Standard 9.5.19.2, this release includes the following enhancement:
Forbade access to tables that belong to partition hierarchies in which bothpg_pathman and standardPostgreSQL inheritance have been used for partitioning. Mixing different partitioning mechanisms in a single table hierarchy is unsupported and should have never been attempted. Previously, you could get duplicated query results from such table hierarchies.
E.1.2. Migration to Version 9.5.20.1
Depending on your current installation, the upgrade procedure will differ.
If you are runningPostgres Pro Standard version 9.5.3.2 or higher, it is enough to install the 9.5.15.1 version into the same directory. However, if you are upgrading fromPostgreSQL 9.5.x or lower versions ofPostgres Pro Standard, some catalog changes should be applied, sopgpro_upgrade script is required to complete the upgrade:
If your database is in the default location,
pgpro_upgradeis run automatically, unless you are prompted to run it manually.If you created your database in a non-default location, you must run
pgpro_upgradescript manually.
Important
Before launchingpgpro_upgrade manually, you must stop thepostgres service. The script must be run on behalf of the user owning the database (typically postgres). Runningpgpro_upgrade as root will result in an error. For details, seepgpro_upgrade.
To migrate to this version from vanillaPostgreSQL 9.5.4 or lower, perform a dump/restore usingpg_dumpall.
