I'm not sure what you are asking here. >> (Incidentally, the comment in hash.h talks about bitmaps but I think >> it means hashm_mapp.) >> > > which comment are you referring here? hashm_mapp contains block > numbers of bitmap pages. The comment I'm referring to says The blknos of these bitmap pages are kept in bitmaps; nmaps is the number of currently existing bitmaps. But there is no "bitmaps" field anywhere. > In the above code, it appears that you are trying to calculate > max_avail space for all pages in same way.

This idea came from btrees. Neither the gin nor the brin code have this. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
