Tom Lane 8f2ea8b7b5 Resurrect heap_deformtuple(), this time implemented as a singly nested ... loop over the fields instead of a loop around heap_getattr. This is considerably faster (O(N) instead of O(N^2)) when there are nulls or varlena fields, since those prevent use of attcacheoff. Replace loops over heap_getattr with heap_deformtuple in situations where all or most of the fields have to be fetched, such as printtup and tuptoaster. Profiling done more than a year ago shows that this should be a nice win for situations involving many-column tables.		2004-06-04 20:35:21 +00:00
