Обсуждение: python - fe: Add support for composite types and arrays(including NULLs

Log Message:
-----------
Add support for composite types and arrays(including NULLs in arrays ;).

This was available before the transition to the new type I/O mapping, but the
initial move broke it. (actually, composites may not have been working at the
time)
