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.
