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

Cause

This issue occurs due to corrupted postmaster.pid file.

Resolution

Location of the postmaster.pid file :-

# ls -l /storage/db/vpostgres/postmaster.pid
-rw------- 1 vpostgres users 45 Oct 30 17:20 /storage/db/vpostgres/postmaster.pid

Try to cat/less on the postmaster.pid file, it will have junk characters.

Move the postmaster.pid file to backup or some other folder
# mv /storage/db/vpostgres/postmaster.pid /storage/db/vpostgres/postmaster.pid_bkp

You should be able to start the vPostgres service now and see a new pid file automatically getting created.

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