Which PG version is this exactly? Given the Memoize node shown
in your plan, I suppose 14.something, but is it up to date?
There were Memoize-related bug fixes in 14.2 and 14.4, and the
one in 14.2 looks particularly likely to be relevant.
If you are on the current minor release, does "set enable_memoize = off"
change the behavior?
