If you migrate to Postgres 13, you will have to upgrade the JDBC driver as well, as Postgres introduced
a new authentication protocol that the outdated JDBC driver does not understand.
The better strategy would probably be to update the driver now and use the current driver with
your Postgres 9.1 installation if you want to test for possible (although unlikely) compatibility
issues with the driver.
