I don't know how. You can't, really. If you haven't vacuumed, you can modify tqual.c, function HeapTupleSatisfiesSnapshot() to always return true, recompile and install that binary, and a SELECT will then show all the rows. Make a backup first, and be sure you use that modified binary only for during recovery. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026
