Hey I think I have found in PG a new sadomasochistic group. Whips! yummy not.

Haha! True, but once you are initiated, you'll be hooked. I know I was when this girlfriend of mine introduced me to bonding, but I digress.

Postgresql's documentation is outstanding, and very easy to search. I suggest you invest some time to get the hang of it, by reading Chapter I Tutorial and investigating Chapter VI Reference, which will cover most your needs.

The pgsql-general list is very active, you'll get all the help you need there, providing you did basic research. I've been reading it every day for twenty years, I learn something new every time.
