Fix inconsistencies in SRF checks of pg_config() and string_to_table()
The execution paths of those functions have been using a set of checks
inconsistent with any other SRF function:
- string_to_table() missed a check on expectedDesc, the tuple descriptor
expected by the caller, that should never be NULL. Introduced in
66f1630.
- pg_config() should check for a ReturnSetInfo, and expectedDesc cannot
be NULL. Its error messages were also inconsistent. Introduced in
a5c43b8.
Extracted from a larger patch by the same author, in preparation for a
larger patch set aimed at refactoring the way tuplestores are created
and checked in SRF functions.
