Subject: [PATCH] Add completion for storage parameters after CREATE TABLE WITH
 in psql
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In passing, move the list of parameters where it can be used for both
CREATE TABLE and ALTER TABLE, and reorder it alphabetically.
