Log Message:
-----------
Don't choke when exec_move_row assigns a synthesized null to a column
that happens to be composite itself. Per bug #5314 from Oleg Serov.

Backpatch to 8.0 --- 7.4 has got too many other shortcomings in
composite-type support to make this worth worrying about in that branch.
