In that case, you'd be a little further better off if the steps were: - drop indices; - copy table to file (perhaps via pg_dump -t my_table); - truncate the table, or drop-and-recreate, both of which make it unnecessary to do _any_ vacuum of the result; - recreate indices, probably with SORT_MEM set high, to minimize paging to disk - analyze the table (no need to vacuum if you haven't created any dead tuples) - cut SORT_MEM back down to "normal" sizes -- output = reverse("gro.gultn" "@" "enworbbc") http://www3.sympatico.ca/cbbrowne/spreadsheets.html Signs of a Klingon Programmer #6: "Debugging?
