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 in 07daca5, for any remaining code paths on sight. Like fcc2817, 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.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
