SQL has more power than most think, and PostgreSQL does a good job in
implementing most of it. Much more than some other well known "free"
databases.
Have a look at http://www.postgresql.org/docs/8.1/static/sql-select.html
and the other SQL commands at
http://www.postgresql.org/docs/8.1/static/sql-commands.html (or your
local copy of the manual).
HTH,
Markus
