It's fairly unlikely anyone will be able to help without you saying what
you're doing. What are these procedures doing? What do the tables look like?
What indexes exist?
At a guess the foreign key relationships you're enforcing don't have indexes
to help them. If they do perhaps postgres isn't using them.
