Мы используем postgresql версии 9.2. При создании резервной копии базы данных с использованием pg_dump мы сталкиваемся с приведенной ниже ошибкой.

Пожалуйста, подскажите мне, как исправить эту проблему.

 pg_dump: [archiver (db)] query was: COPY public.aclappliedtopep (id, instance_version, direction, aclname, ifname, owningentityid, protocolendpoint_id, deploypending, authentityid, authentityclass, accesscontrollist_id) TO stdout;
pg_dump: FATAL:  terminating connection due to administrator command
pg_dump: [archiver (db)] query failed: server closed the connection unexpectedly
                This probably means the server terminated abnormally
                before or while processing the request.
pg_dump: [archiver (db)] query was: COPY public.aclappliedtopep (id, instance_version, direction, aclname, ifname, owningentityid, protocolendpoint_id, deploypending, authentityid, authentityclass, accesscontrollist_id) TO stdout;
pg_dump: [archiver (db)] connection to database "qovr" failed: could not connect to server: Connection refused
                Is the server running on host "localhost" (127.0.0.1) and accepting
                TCP/IP connections on port 5433?
