range/range partition

Hi everybody:

I am trying to create a table partitioned by range/range - that is partition by range by column1 and subpartition by range by column2. My command is erroring out and I don't see anything about range/range partition in the manual
(I only see range/list and range/hash). The manual does describe the range partitioning by multiple columns.
Is that what I need to do instead of range/range partitioning?

thank you

Gene Gurevich
