Then just add the logic to run it from your init script. If you're
running something like ubuntu there's a script in /etc/init.d to start
postgres you can hack up to add a new step at the end. Not sure
that's the best place but it'll work.

If you just need each new db to have certain tables, then put them in
template1 and when you create a new db they'll be there. As is often
the case, instead of asking how to do very specific things, you're
better off telling us what you're trying to accomplish in the bigger
sense so we can recommend better ways to accomplish what you want.
Note that PostgreSQL does NOT support triggers on system tables and
objects so you'll have to find some way of monitoring pg logs if you
want to know when things like new tables are created. Again, give us
the bigger picture and we can likely be more helpful.
