Thanks Stephen for your advice Iam running the VACUUM command from 2 of
the linux instances using the below command. We were running some scripts
from these linux boxes and surprised to see 1 works the other does not so
wondering why does it happen.

* Command:* *VACUUM VERBOSE myTableTest;*

1) Running from Linux Instance1
Command Iam running -> psql -h clusterName -U myUserName -d myPostgresDB
There is no .pgpass setup on this linux instance so I had to manually enter
the password here. VACUUM on the table Iam running does not work and throws
an error as ERROR: cannot execute VACUUM during recovery
2) Running from Linux Instance2
Command Iam running -> psql -d myPostgresDB -h clusterName -U myUserName
This option had a .pgpass file at the root in this linux instance and I did
not pass any password here, the
*VACUUM on the table Iam running works.*

*pgpass is setup here and contains
-> clusterName:5432:myPostgresDB:myUserName:myDBPassword*

Thanks
- Kran.
