Question : Asterisk and Postgresql

Hey,

I'm a newbie when it comes to Linux so please bare with me.

I've installed asterisk, and I noticed some of the psql libraries are available; after doing a quick search I have:
/usr/bin/psql
/usr/lib/pgsql
/usr/include/pgsql
/usr/include/postgres_ext.h

Is it possible that asterisk installs the necessary libraries and if so, how can I send sql queries?  FYI: psql command does not work.

Thanks,
Kathryn

You need postgresql-server rpm or use yum
