           Note
           role, replication_delay, last_status_change out parameters are new from Pgpool-II 4.0.
           If you have already installed pre-4.0 pgpool_adm extension, you can upgrade to the new
           one by using ALTER EXTENSION SQL command.

                    ALTER EXTENSION pgpool_adm UPDATE;

           Note
           replication_state and replication_sync_state out parameters are new from Pgpool-II
           4.1. If you have already installed pre-4.1 pgpool_adm extension, you can upgrade to
           the new one by using ALTER EXTENSION SQL command.

                    ALTER EXTENSION pgpool_adm UPDATE;

           Note
           pg_status, pg_role out parameters are new from Pgpool-II 4.3. If you have already
