I should have also mentioned to try the EXPLAIN EXECUTE six times and
see if the last one produces a different plan. That's when it switches
from planning every time to planning with generic arguments, as I
recall.

That wasn't advice actually, just a note that the code might be doing
that thing wrong, causing auto_explain to miss it. This is an unproven
hypothesis that is likely to be all wrong.
