Re: How to check postgres running or not ?

Assuming it is unix.... The command

ps xau|grep post

If it is running it will produce output like...

worik(at)stolberg:~$ ps xau|grep post
postgres 880 0.0 0.2 8580 740 ? S Sep07 0:31
/usr/lib/postgresql/bin/postmaster
postgres 887 0.0 0.2 9536 612 ? S Sep07 0:02 postgres:
stats buffer process
postgres 889 0.0 0.2 8624 632 ? S Sep07 0:05 postgres:
stats collector process
worik 25927 0.0 0.2 1612 540 pts/10 S 13:54 0:00 grep post
worik(at)stolberg:~$

If it is not running it will produce output like...

worik(at)stolberg:~$ ps xau|grep post
worik 26094 0.0 0.2 1608 528 pts/10 S 13:55 0:00 grep post
