This makes more consistent the SRF-related checks in the area of PL/pgSQL, PL/Perl, PL/Tcl, pageinspect and some of the JSON worker functions, making it easier to grep for the same error patterns through the code, reducing a bit the translation work. It is worth noting that each_worker_jsonb()/each_worker() in jsonfuncs.c and pageinspect's brin_page_items() were doing a check on expectedDesc that is not required as they fetch their tuple descriptor directly from get_call_result_type(). This looks like a set of copy-paste errors that have spread over the years. This commit is a continuation of the changes begun in07daca5, for any remaining code paths on sight. Likefcc2817, this makes the code more consistent, easing the integration of a larger patch that will refactor the way tuplestores are created and checked in a good portion of the set-returning functions present in core. I have worked my way through the changes of this patch by myself, and Ranier has proposed the same changes in a different thread in parallel, though there were some inconsistencies related in expectedDesc in what was proposed by him.
