Try SET CONSTRAINTS ALL IMMEDIATE and then EXPLAIN ANALYZE the
delete.  This should cause all the triggers to run within the
scope of the EXPLAIN ANALYZE, and you'll be able to see which
one(s) are slow.  (This assumes you're running a recent release
of PG; I think EXPLAIN shows trigger times since 8.1 or so.)
