These functions should be called at most once per ResultRelInfo; it's wasteful to do otherwise, and certainly the pattern of opening twice and then closing twice is a bad idea. Moreover, aminsertcleanup functions might not be prepared to be called twice, as the just-hardened code in BRIN demonstrates. This amounts to an API change, since such coding patterns were safe even if wasteful before v17. Hence, apply to HEAD only. (Extension code violating this new rule faces some risk in v17, but we just fixed brininsertcleanup and there are probably few other aminsertcleanup functions as yet. So the odds of breaking usable code seem higher than the odds of doing something useful with a back-patch.)
