Thread: pgsql: amcheck: Distinguish interrupted page deletion from corruption.
amcheck: Distinguish interrupted page deletion from corruption. This prevents false-positive reports about "the first child of leftmost target page is not leftmost of its level", "block %u is not leftmost" and "left link/right link pair". They appeared if amcheck ran before VACUUM cleaned things, after a cluster exited recovery between the first-stage and second-stage WAL records of a deletion. Back-patch to v11 (all supported versions). Reviewed by Peter Geoghegan.
