Обсуждение: pgsql: Remove hastup from LVPagePruneState.

Remove hastup from LVPagePruneState.

Instead, just have lazy_scan_prune() and lazy_scan_noprune() update
LVRelState->nonempty_pages directly. This makes the two functions
more similar and also removes makes lazy_scan_noprune need one fewer
output parameters.
