        o -ALTER TABLE ADD COLUMN does not honor DEFAULT and non-CHECK CONSTRAINT
        o -ALTER TABLE ADD COLUMN column DEFAULT should fill existing
          rows with DEFAULT value
        o -Allow ALTER TABLE to modify column lengths and change to binary
          compatible types

Remove:

        o Allow columns to be reordered using ALTER ... POSITION i col1 [,col2];
          have SELECT * and INSERT honor such ordering

* ALTER ... ADD COLUMN with defaults and NOT NULL constraints works per SQL
spec.  A default is implemented by rewriting the table with the new value
stored in each row.

* ALTER COLUMN TYPE.  You can change a column's datatype to anything you
want, so long as you can specify how to convert the old value.  Rewrites
the table.  (Possible future improvement: optimize no-op conversions such
as varchar(N) to varchar(N+1).)

* Multiple ALTER actions in a single ALTER TABLE command.  You can perform
any number of column additions, type changes, and constraint additions with
only one pass over the table contents.

Basic documentation provided in ALTER TABLE ref page, but some more docs
work is needed.
