Hi, When we create a range partitioned table, we cannot use a column more than once in the partition key.
postgres=# create table t (i int) partition by range(i,i); ERROR: column "i" appears more than once in partition key However, I can use same expression more than once in partition key. postgres=# create table t (i int) partition by range((i),(i)); CREATE TABLE Although this can be blocked by the attached parch, for example, the following is still possible. postgres=# create table t (i int) partition by range((i),i); CREATE TABLE Can these definition be a problem in the internal of partitioning? If not, we might not need to check column that apears more than once in the partition key.
