In writeListPage, never take a full-page image of the page, because we have all the information required to re-initialize in the WAL record anyway. Before this fix, a full-page image was always generated, unless full_page_writes=off, because when the page is initialized its LSN is always 0. In stable-branches, keep the code to restore the backup blocks if they exist, in case that the WAL is generated with an older minor version, but in master Assert that there are no full-page images. In the redo routine, add missing "off++". Otherwise the tuples are added to the page in reverse order. That happens to be harmless because we always scan and remove all the tuples together, but it was clearly wrong. Also, it was masked by the first bug unless full_page_writes=off, because the page was always restored from a full-page image. Backpatch to all supported versions. |
