Instead of

  create or replace table t1 (x int)
  partition by range(x) (
    partition p1 values less than (10),
    partition pn values less than maxvalue);

it should be possible to type in shorter form:

  create or replace table t1 (x int)
  partition by range(x) (
    p1 values less than (10),
    pn values less than maxvalue);

As above examples demonstrate, make PARTITION keyword in partition
definition optional.
