Upgrade Percona Distribution for PostgreSQL

There are two types of PostgreSQL upgrades available through the Operator:

  • Minor upgrade is upgrading within the same major version. For example, from 15.5 to 15.7 or from 16.1 to 16.3.
  • Major upgrade is upgrading across major versions, such as from 15.5 to 16.3.

Major upgrades are supported starting from Operator 2.4.0 as a tech preview. Starting with Operator 2.9.0, major upgrades are generally available (GA) and fully supported.

Before Operator 2.4.0, only minor upgrades were allowed.
