Oh, right, I missed that.

That seems pretty mysterious then.  But is it possible the function is
getting called more times than it should?  I notice that it's set up
as a trigger; is it FOR EACH ROW when it should be a statement-level
trigger or something like that?  Maybe run EXPLAIN ANALYZE on the
query that's invoking the trigger to get some more detail on what's
going on?
