If we recursed to a new call of the same function, with a different coldeflist (AS clause), it would fail because the inner call would overwrite the outer call's idea of what to return. This is vaguely like 1d2fe56e4 and c5bec5426, but it's not due to any API decisions: it's just that we computed the actual output rowtype at the start of the call, and saved it in the per-procedure data structure. We can fix it at basically zero cost by doing the computation at the end of each call instead of the start. It's not clear that there's any real-world use-case for such a function, but given that it doesn't cost anything to fix, it'd be silly not to. Per report from Andreas Karlsson. Back-patch to all supported branches. Discussion: https://postgr.es/m/1651a46d-3c15-4028-a8c1-d74937b54e19@proxel.se
