[GENERAL] pg_dump pg_restore hanging in CentOS for large data

Hi ,

   I am facing an issue with backup/Restore for data size more than 2GB. Its working fine for 1GB.

Below are the details for issue:

Description:

The command pg_dump is hanging at saving large objects and process gets terminated after some time.

The command pg_restore is hanging at executing BLOB and getting terminated after some time.

Expecting: pg_dump/pg_restore should work for minimum large data size <20GB.

PostgreSQL version number you are running: postgres92-9.2.9-1.x86_64

 How you installed PostgreSQL:

      Linux RHEL(Backup) installed using rpm. 

             CentOS7.2(Restore) installed using yum. 

 Operating system and version: 

      Backup - Red Hat Enterprise Linux Server release 5.4 (Tikanga)

             Restore -centos-release-7-2.1511.el7.centos.2.10.x86_64

What program you're using to connect to PostgreSQL: pg_dump/pg_restore using shell script

Is there anything relevant or unusual in the PostgreSQL server logs?:

          Pg_dump verbose log: stuck after: pg_dump: saving large objects

                        Pg_restore verbose log: Stuck after: pg_restore: restoring large objects

                                Some times: pg_restore: pg_restore: processing item 4376515 BLOB 4993394

                                            pg_restore: executing BLOB 4993394

For questions about any kind of error:

What you were doing when the error happened / how to cause the error: Tried options pg_dump using split and restore. Still same issue exists.

The EXACT TEXT of the error message you're getting, if there is one: (Copy and paste the message to the email, do not send a screenshot)

-          No specific error, pg_dump/pg_restore getting terminated for data >2GB
