Tom Lane 6889303531 Redefine the lp_flags field of item pointers as having four states, rather ... than two independent bits (one of which was never used in heap pages anyway, or at least hadn't been in a very long time). This gives us flexibility to add the HOT notions of redirected and dead item pointers without requiring anything so klugy as magic values of lp_off and lp_len. The state values are chosen so that for the states currently in use (pre-HOT) there is no change in the physical representation.		2007-09-12 22:10:26 +00:00
