Hmm. But all functions verify multiple levels. What distinguishes bt_index_parent_check()'s verification is that the downlinks in internal pages are checked against actual child pages (every item in the child page, in fact). It's the parent/child relationship that is verified in addition to the standard checks of every page on and across (not between) every level. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
