Tines now supports PostgreSQL 14, from Tines v15.0 onwards.
Note: Since PostgreSQL 11 will be unsupported after November 9, 2023, we will be discontinuing support for PostgreSQL 11.x in version 19.0. Any 18.x or older versions will still support PostgreSQL 11.x.
You can find instructions for upgrading here depending on your installation type:
