vPostgres service fails to start with Fatal error : bogus postmaster.pid

I came across this issue today where vPostgres service was failing on VCSA with error Fatal Error.

# service-control --start vmware-vpostgres
Perform start operation. vmon_profile=None, svc_names=['vmware-vpostgres'], include_coreossvcs=False, include_leafossvcs=False
2019-11-06T21:38:14.283Z   Service vmware-vpostgres state STOPPED

            ],
            "id": "install.ciscommon.service.failstart",
            "localized": "An error occurred while starting service 'vmware-vpostgres'",
            "translatable": "An error occurred while starting service '%(0)s'"
        }
    ],
    "componentKey": null,

2019-11-06 21:38:14.700 UTC 5dc33d46.eeff 0   FATAL:  bogus data in lock file "postmaster.pid": ""

Location of the postmaster.pid file :-

root@vcenterdr [ /var/log/vmware/vpostgres ]# ls -l /storage/db/vpostgres/postmaster.pid
-rw------- 1 vpostgres users 45 Oct 30 17:20 /storage/db/vpostgres/postmaster.pid

I tried to cat/less the postmaster.pid file and found that it had junk characters.

After moving this pid file, vPosgres service started fine and automatically created fresh pid file.

# mv /storage/db/vpostgres/postmaster.pid /storage/db/vpostgres/postmaster.pid_bkp


Note :- Please do not delete the file, and take proper snapshot/backup before making changes
