It is not that hard to implement, just messy. When the index returns a heap row and the heap row is viewed for visibility, if _no_one_ can see the row, the index can be marked as expired. It could be a single bit in the index tuple, and doesn't need to be flushed to disk, though the index page has to be marked as dirty. However, we are going to need to flush a pre-change image to WAL so it may as well be handled as a normal index page change. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026 ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
