Does PostgreSQL support standard conforming strings?

        # error messages in the logs when working on a PostgreSQL database server that
        # does not support standard conforming strings.

        # postgres-pr does not raise an exception when client_min_messages is set higher
        # than error and "SHOW standard_conforming_strings" fails, but returns an empty
        # PGresult instead.
