Thanks, Tom. I'll look forward to 8.3.
If I understand correctly, TRUNCATE is equivalent to DELETE FROM. My problem was that I also needed to reset the serial attribute. My solution was the following
-- clear and reset counter
delete from dom1_classid_sorted_temp;
perform setval('dom1_classid_sorted_temp_class_rank_dom_seq'::regclass,1,false);
Thanks again.
Best,
david

I think the problem is here:

plpgsql tries to cache plans for its queries, and dropping a table
invalidates any already-made plans for that table. Can you TRUNCATE
the table instead?
PG 8.3 will be smarter about this sort of thing.
