I'm afraid that I've misunderstood the discussion. Do you mean that
per-table options should be stored in reloptions, but per-column should
be separated from attoptions? (I think I've misread...)

Could you tell me little more detail why it doesn't make sense to have
table reloptions separate from table FDW options?
