Subject: [PATCH 1/2] [ticket/17148] Fix sql_table_exists() error for
 PostgreSQL 9.3 and earlier

PostgreSQL 9.3 and earlier versions don't support Empty SELECT lists
(support was added since v. 9.4).
Also add PostgreSQL 9.3 tests as earlier images fail in current tests env.

Subject: [PATCH 2/2] [ticket/17148] Bump PostgreSQL minimum requirement to
 9.4+

master branch uses Doctrine 3 which provides specific platform
only for PostgreSQL 9.4 and above.
Also bump maximum PHP requirement to PHP 8.2 as it is infact.
