I've applied a fix for this.

The fix actually uses the "expected tuple desc" that's now passed by
ExecMakeTableFunctionResult as the target descriptor.  This should mean
that it'd be possible to support plpgsql functions returning RECORD, but
I didn't have time to look into that.  Anyone want to try?
