By the way, I'm really glad you hit that error. That particular error

to understand, and it sounds like it is doing its job as intended.
Having problems isn't great, but knowing that you have problems is a
lot better than still having them but not knowing about it.
That’s exactly what concerns me. I see it as a potential design flaw if
the extension has to make assumptions about possible plan configurations.
I’m not sure how it works in detail, of course. However, when I designed
Postgres replanning in the past, and made similar core changes to what
you’ve done for pg_plan_advice, this kind of problem couldn’t have
happened. So, I think it’s worth questioning the current approach and
looking for other options.
