Well, you can do this 2 ways:
1) you can pick out one query at a time, and send us complete information on
it, like Matt's really nice e-mail describes. People on this list will
help you troubleshoot it. It will take a lot of time, but no money.
2) You can hire a PG database expert. This will be much faster, but cost
you a lot of money.

Complex queries? Large databases? That's us. MySQL is obtimized for
simple queries on small databases.
