That would not be as easy as for ViewOptions. For example as for the current
master code, fillfactor from StdRdOptions is used in Toast, Heap, Hash index,
nbtree index, and spgist index. This will make RelationGetFillFactor macros a
bit complicated for example.
Now I have patches that limits usage of StdRdOptions to Heap and Toast.
When StdRdOptions is not that widely used, we whould be able to add asserts
for it, it will not make the code too complex.
So I would suggest to do ViewOptions asserts now, and keep dealing with
StdRdOptions for later. When we are finished with my current patches, I will
take care about it.
