CREATE TABLE does not require PARTITION to be a reserved keyword,
but there are conflicts in ALTER TABLE ADD/DROP PARTITION:

  * ALTER TABLE ... DROP [COLUMN]  name [CASCADE | RESTRICT]
  * ALTER TABLE ... DROP PARTITION name [CASCADE | RESTRICT]

There are some solutions:

 1. Change COLUMN not to an optional word (unlikely)
 2. Change syntax of DROP PARTITION to DROP TABLE PARITION or so
 3. Change ALTER TABLE ADD/DROP PARTITION to top level 
      => CREATE/DROP PARTITION name ON table_name

Any better ideas?
