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
Abu
