[MADLIB-851] DBConnector cannot handle return type RECORD without tuple descriptor provided at call time

Description

Reproducing:

• write an UDF (e.g. foo) returns RECORD using C++ AL
• call:

  SELECT foo();

Debugging:
In file SystemInformation_impl.hpp, the case that get_call_result_type() returns NULL is not handled correctly.

Work-around:
Can be worked around by giving the tuple descriptor "func(...) AS t(...)".
