Error while using pg_dump

Hi All,

We are facing below error while taking the backup of the database using
pg_dump. Could you suggest me how to rectify this?

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;

dollar qustion is 1

dbuser name is qovr , dbname is qovr and direcotry is
/opt/tempbackups/HCS-SYD3-PCA01-weekly-backup/backup/appcomponent/qovr-db/emms_db_09_05_17_18_46_26.dump

dollar qustion is 0

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)] 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?
