This patch adds a way of iterating through the members of a bitmapset nondestructively, unlike the old way with bms_first_member(). While bms_next_member() is very slightly slower than bms_first_member() (at least for typical-size bitmapsets), eliminating the need to palloc and pfree a temporary copy of the target bitmapset is a significant win. So this method should be preferred in all cases where a temporary copy would be necessary. Tom Lane, with suggestions from Dean Rasheed and David Rowley |
