postmaster dead but pid file exists
Cause : To get a better idea on why postgres is not starting we can check the pgsql log under /var/log
# cd /var/log
# cd /var/log
# less pgsql
The above message states that database is not able to write any more to /tmp/s.PGSQL.5432.lock since there is no space left in "/tmp"
We can do df -h to confirm the space.

The above message states that database is not able to write any more to /tmp/s.PGSQL.5432.lock since there is no space left in "/tmp"
We can do df -h to confirm the space.
Resolution : Clear up the old files in "/tmp" directory. We can use rm -rf command to clear files. Once we get free space under "/tmp" we can try restarting the postgres service.
