8.2.3. DDL statements with restrictions

ALTER TABLE

     Generally ALTER TABLE commands are allowed. There are a however
several sub-commands that are not supported, mainly those that perform a
full-table re-write.

ALTER COLUMN ... TYPE - changing a column's type is not supported.
Chaning a column in a way that doesn't require table rewrites may be
suppported at some point.
