I'd try "DELETE FROM pg_statistic". If that doesn't complain, the normal process would be to VACUUM pg_statistic and then re-ANALYZE the database, but since you're just trying to dump data you might be able to skip that bit. > I shut down the 7.4 database and ran pg_resetxlog.

Good, because that wasn't a very bright move --- I can't imagine that the shutdown checkpoint would have worked, and pg_resetxlog after an unclean shutdown is a recipe for losing data. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
