Supported databases

We officially only support the databases and versions listed in the table, as these are tested in the CI.
Since the package is based on doctrine dbal, other databases such as OracleDB and MSSQL may also work.
But we can only really support the databases if we can also automatically ensure that they don't break due to changes.

[!TIP]
We recommend using PostgreSQL.

Database	Version
PostgreSQL	14.20, 15.15, 16.11, 17.7, 18.1
MariaDB	10.6, 10.11, 11.4, 11.8, 12.1
MySQL	8.0, 8.4, 9.5
SQLite	3.x
