Subject: pgsql: Keep all_frozen updated in heap_page_prune_and_freeze
Date: Thu, 20 Nov 2025 16:04:59 +0000
Message-ID: <E1vM79W-000UmN-2K@gemulon.postgresql.org> (raw)
Keep all_frozen updated in heap_page_prune_and_freeze
Previously, we relied on all_visible and all_frozen being used together
to ensure that all_frozen was correct, but it is better to keep both
fields updated.
Future changes will separate their usage, so we should not depend on
all_visible for the validity of all_frozen.
