If you have a recent version of Postgresql, you can do an
EXPLAIN ANALYZE before the actual query:

EXPLAIN ANALYZE SELECT (*) FROM mytable WHERE foo=12;

Alteratively, I wrote a small patch for psql that tells
you how long every query you run takes. It may not work
on your version: please always state which version you
are running when posting a question. If you want to use my
patch and it does not work with your version, let me know
and I'll tweak it so it does.
