Attached is an idea of patch for the documentation, using this wording: + <listitem> + <para> + When defining a primary key on a partitioned table, the primary + key column must be included in the partition key. + </para> + </listitem> If somebody has any better idea for that paragraph, please feel free.
Reads a bit backward. How about:
"As uniqueness can only be enforced within an individual partition when defining a primary key on a partitioned table all columns present in the partition key must also exist in the primary key."
