MD3 - PostgreSQL version older than 14 are deprecated

Since Removed
3.3.0 3.5.0

This notice is raised when MAAS is using a PostgreSQL version older than 14.

Use of PostgreSQL 12 deprecated in MAAS 3.3

Up to the 3.2 versions of MAAS, the default PostgreSQL version in use was 12 (older versions were no longer supported).

Starting from 3.3, with MAAS running on 22.04, the default 22.04 version of Postgres (14) is the default, and older versions are deprecated.

PostgreSQL 12-based installs of 3.3 will still work correctly, but support for version 12 will be dropped in MAAS 3.5.

See the upgrade procedure for a detailed description on how to perform the PostgreSQL upgrade.
