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?
