Feature request: Reget oid of tables/views when doing a reload

When I'm doing heavy development I'm always removing and recreating 
tables and views.

If you
- drop a view
- create a view with the same name
- and have the data window for the view open from before it was dropped
- and do a refresh

You lose the column names, since the oid for the view/table is cached.  
So if upon refresh, it rechecked the oid of the thing you are viewing, 
that would fix the issue.
