in bufpage.h: "all blocks written out by an access method must be disk pages"
but in http://www.postgresql.org/docs/8.4/static/storage-page-layout.html "Actually, index access methods need not use this page format. All the existing index methods do use this basic format, but the data kept on index metapages usually doesn't follow the item layout rules." I'm not getting it: am I supposed to use the "disk page format" when writing an index access method, or it's just a "good practice" because it makes the handling easier? Given the docs it looks "recommended", but the comment on the code sounds more "mandatory". -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
