Subj:   Re: Partitioning on different column to PI
 
From:   Prescott, Kyle R

It is possible for NUPI (non-unique primary index). You can add a partitioning column that is not a part of the primary index.

However for UPI (unique primary index), the partitioning column has to be a part of the key. This is so that the RDBMS only looks on the current target AMP to check for duplicates.
