You can circumvent this by setting a 'server_version' configuration value

Hello,
I am trying to use postgres with nettrine and I get the error above.
I tryied this configuration:

dbal: #doctrine
        connection:
                driver: pdo_pgsql
                host: localhost
                dbname: test
                user: user
                password:
                server_version: 11.7

but without success :( Any idea how to configure server_version for doctrine?
