The problem with constraints in ExecRelCheck() I've just found not only affects COPY. It also occurs with INSERT...SELECT or big UPDATE's. Constraints with many affected tuples eat up backend memory quickly until out of swap space. This fix must go into CURRENT and REL6_4 before we release v6.5 or v6.4.3 either. There are actually reports from users not able to reload dumps made with v6.4.2.
