What's the best way to ensure that Pg is running from a shell script?
I'm crafting a few RPMs for my projects, one of which will attempt to
load data into a database, but I want to check that it's running first
before I try this.
I'm a shell scripting newbie so apologies if the answer is really
straightforward. I don't know if UNIX processes leave a standard trail
so that I could just look up if something is listening on 5432, for
example.
Thanks,
Fran
