Tom Lane	cb8b6618ce	Revise pgstats stuff to fix the problems with not counting accesses ... generated by bitmap index scans. Along the way, simplify and speed up the code for counting sequential and index scans; it was both confusing and inefficient to be taking care of that in the per-tuple loops, IMHO. initdb forced because of internal changes in pg_stat view definitions.	21 years ago
Tom Lane	278bd0cc22	For some reason access/tupmacs.h has been #including utils/memutils.h, ... which is neither needed by nor related to that header. Remove the bogus inclusion and instead include the header in those C files that actually need it. Also fix unnecessary inclusions and bad inclusion order in tsearch2 files.	21 years ago
Tom Lane	4a8c5d0375	Create executor and planner-backend support for decoupled heap and index ... 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.	21 years ago
