It's not PL/pgSQL's fault here. The pg_proc entries are created by the CREATE FUNCTION utility command
that's used for all languages. So what we're talking about affects SQL, C, PL/Tcl, PL/Perl, PL/Python and whatnot
too.PL/pgSQL might live with that very well, because it has some automatic type conversion (using the actual
valuestypoutput and the needed types typinput functions) to convert values on the fly. But a C function
receivinga different type all of a sudden is a good candidate to coredump the backend.
