python - be: Change error signalling of - Mailing list pgsql-committers

Log Message:
-----------
Change error signalling of HeapTuple_FromTupleDescAndIterable.

Return NULL and set the Python exception instead of letting a PostgreSQL error
raise.

Also, check the results of functions to handle errors properly. Don't use
Datum_FromTypeOidAndPyObject. This will save a datumCopy in some cases.

Update callers of the function to respect the change.
