Answer 1

PostgreSQL has this feature. Just add this to the end of your table definition:

INHERITS FROM (tablename[, othertable...])

The child table will have all the columns of its parent, and changes to the parent table will change the child. Also, everything in the child table will come up in queries to the parent table (by default). Unfortunately indices don't cross the parent/child border, which also means you can't make sure that certain columns are unique across both the parent and child.

As far as I know, it's not a feature used very often.
