    I was looking at derby's upgrade script and it seems to be using NOT NULL.
    Does "NOT NULL" result in a syntax error?
    If so, perhaps we should add this column without null qualifier and then later set this column as "not null" as listed at http://www.postgresql.org/docs/8.0/static/sql-altertable.html
