2005-10-15	Standard pgindent run for 8.1.	Bruce Momjian

2005-08-28	Tweak nodeBitmapAnd to stop evaluating sub-plan scans if it finds it's	Tom Lane
	got an empty bitmap after any step; the remaining subplans can no longer affect the result. Per a suggestion from Ilia Kantor.
2005-04-20	Minor performance improvement: avoid unnecessary creation/unioning of	Tom Lane
	bitmaps for multiple indexscans. Instead just let each indexscan add TIDs directly into the BitmapOr node's result bitmap.
2005-04-19	Create executor and planner-backend support for decoupled heap and index	Tom Lane
	scans, using in-memory tuple ID bitmaps as the intermediary. The planner frontend (path creation and cost estimation) is not there yet, so none of this code can be executed. I have tested it using some hacked planner code that is far too ugly to see the light of day, however. Committing now so that the bulk of the infrastructure changes go in before the tree drifts under me.
