I have partitioned a table based on period (e.g., cdate >= '2007-01-01'::date and cdate<=.2007-03-31':;date).
Now, I am issuing query like cdate >= CURRENT_DATE - 1 and cdate <= CURRENT_DATE, it scans all the partitions. But if I do cdate >= '2007-01-01'::date and cdate<=.2007-03-31'::date it picks the correct partition. Also if I join the cdate field with another table, it does not pick the correct partition.
I would like to know if it is possible to pick the correct partition using the above example.
Thanks
