Where's the Database?

Hey List;

I've been really getting into PostgreSQL attempting to rewrite my current
website ( www.HireLiveMusicians.com ) with a DB backend.  The site is
working on flat text files currently.  My question is for archiving/backing
up  and just general knowledge, where are my databases being stored by
default.  I've been creating the database logged on a specific user not
root.  I'm just curious, I know that I'm supposed to write scripts to create
the tables, triggers, indexes, etc and then import my exported data back
into the tables if something runs amiss.

TIA

Mike
