Tomas Vondra 7db0cd2145 Set PD_ALL_VISIBLE and visibility map bits in COPY FREEZE ... Make sure COPY FREEZE marks the pages as PD_ALL_VISIBLE and updates the visibility map. Until now we only marked individual tuples as frozen, but page-level flags were not updated, so the first VACUUM after the COPY FREEZE had to rewrite the whole table. This is a fairly old patch, and multiple people worked on it. The first version was written by Jeff Janes, and then reworked by Pavan Deolasee and Anastasia Lubennikova.
