Revise pgstats stuff to fix the problems with not counting accesses
Tom Lane <tgl@sss.pgh.pa.us>
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.
