From ccbb07d92229a3ebdfbb129aafaba99a22658403 Mon Sep 17 00:00:00 2001 From: Bruce Momjian <bruce@momjian.us> Date: Fri, 22 Apr 2005 15:40:16 +0000 Subject: [PATCH] Fix typo: < Currently indexes do not have enough tuple tuple visibility < information to allow data to be pulled from the index without < also accessing the heap. One way to allow this is to set a bit < to index tuples to indicate if a tuple is currently visible to < all transactions when the first valid heap lookup happens. This < bit would have to be cleared when a heap tuple is expired. > Currently indexes do not have enough tuple visibility information > to allow data to be pulled from the index without also accessing > the heap.
