Обсуждение: pgsql: Prefix PruneState->all_{visible,frozen} with set_

Prefix PruneState->all_{visible,frozen} with set_

The PruneState had members called "all_visible" and "all_frozen" which
reflect not the current state of the page but the state it could be in
once pruning and freezing have been executed. These are then saved in
the PruneFreezeResult so the caller can set the VM accordingly.

Prefix the PruneState members as well as the corresponsding
PruneFreezeResult members with "set_" to clarify that they represent the
proposed state of the all-visible and all-frozen bits for a heap page in
the visibility map, not the current state.
