The out-of-order problems you're seeing can be fixed by hand-editing the dump file, which is a major pain in the butt but one which will go away with 7.1 or maybe 7.0.3 (? not sure if this includes the new version of pg_dump).
Doing a restore shouldn't break AOLserver, unless you're deleting and restoring the actual database being used by it. So that's a mystery. It clearly shouldn't break Postgres, either, and if you have real breakage you should submit a bug report to the Postgres development group complete with an offer to supply the dump file that breaks it.
