It is not the executor's business to know about defaults.  The rewriter
is the place where defaults get inserted - see rewriteTargetList().

Note that default NULL will have to be treated a little differently from
what we do for INSERT, since the, um, default behavior of UPDATE is to
preserve columns rather than replace 'em with nulls.
