Re: How to check postgres running or not ?

Well, the way I usually check on what databases are running is thus:

cbbrowne(at)wolfe:/tmp/mm5/doc> netstat -an | grep PG Saturday 13:18:30
unix 2 [ ACC ] STREAM LISTENING 2793 /var/run/postgresql/.s.PGSQL.5432

One could presumably script things further to get more out of that; it
doesn't normally seem worthwhile to do so...
