Log Message:
-----------
Adjust ExecMakeTableFunctionResult to produce a single all-nulls row
when a function that returns a single tuple (not a setof tuple) returns
NULL.  This seems to be the most consistent behavior.  It would have
taken a bit less code to make it return an empty table (zero rows) but
ISTM a non-SETOF function ought always return exactly one row.  Per
bug report from Ivan-Sun1.
