Add integrity-checking functions to pg_visibility.
Robert Haas <rhaas@postgresql.org>
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. Amit Kapila and Robert Haas, reviewed (in earlier versions) by Andres Freund. Additional testing help by Thomas Munro.
