Wouldn't be a big deal --- yes, accept_weak_input would need a bit of
modification, but it's not much.  The main reason I suggested it was
that a GUC would be subject to RESET ALL and so it'd fix the pooler
hazard you pointed out.

No, we'd need to create an update script that uses ALTER FUNCTION.
Extension scripts are basically frozen once shipped.
