What would be useful, for this case, would be to provide the query
plan, perhaps via
EXPLAIN [Big Long Query].
The difference between that EXPLAIN and what you get on 7.4 might be
quite interesting.
I would think it quite unlikely that it is truly an "infinite" loop;
it is rather more likely that the plan winds up being pretty bad and
doing something [a bunch of nested loops, maybe?] that run longer than
your patience will permit.
