With memoize enabled PG14 append tests produce a very different plan compared to previous PG versions. To make comparing plans between PG versions easier we disable memoize for PG14. PG14 also modified how EXTRACT is shown in EXPLAIN output so any query using EXTRACT will have different EXPLAIN output between PG14 and previous versions.
