Tom Lane	c398300330	Combine cmin and cmax fields of HeapTupleHeaders into a single field, by ... keeping private state in each backend that has inserted and deleted the same tuple during its current top-level transaction. This is sufficient since there is no need to be able to determine the cmin/cmax from any other transaction. This gets us back down to 23-byte headers, removing a penalty paid in 8.0 to support subtransactions. Patch by Heikki Linnakangas, with minor revisions by moi, following a design hashed out awhile back on the pghackers list.	2007-02-09 03:35:35 +00:00
