Robert Haas	e472ce9624	Add integrity-checking functions to pg_visibility. The new pg_check_visible() and pg_check_frozen() functions can be used to verify that the visibility map bits for a relation's data pages match the actual state of the tuples on those pages.

Robert Haas	ba0a198fb1	Add pg_visibility contrib module. This lets you examine the visibility map as well as page-level visibility information. I initially wrote it as a debugging aid, but was encouraged to polish it for commit. Patch by me, reviewed by Masahiko Sawada. Discussion: 56D77803.6080503@BlueTreble.com	2016-03-08 08:42:01 -05:00
