Re: VERY SMALL DOC BUG: http://www.postgresql.org/idocs/index.php?sql-createtable.html

Looks like this is already fixed in 7.3, due out in a few months:

A not-null constraint is always written as a column constraint. A
not-null constraint is equivalent to creating a check constraint
<literal>CHECK (<replaceable>column_name</replaceable> IS NOT
NULL)</literal>, but in <productname>PostgreSQL</productname>
