Hi,I have some 99,000 records in a table (OBSERVATION_ALL) in a Postgres DB as well as a Greenplum DB.The Primary key is a composite one comprising of 2 columns (so_no, serial_no).The execution of the following query takes 8214.016 ms in Greenplum but only 729.134 ms in Postgres.select * from observation_all order by so_no, serial_no;I believe that execution time in greenplum should be less compared to postgres. Can anybody throw some light, it would be of great help.Regards,
Suvankar Roy
