probably below statements will explines you that.. 

The deduplication database stores and manages the metadata of
deduplicated files. The metadata includes a unique fingerprint
that identifies the file’s content. The metadata also includes
information about the file such as its owner, where it resides on
a client, when it was created, and other information.
NetBackup uses the PostgresSQL database for the deduplication
You can use the NetBackup bpps command to view the database
process (postgres).
The deduplication database is separate from the NetBackup
catalog. The NetBackup catalog maintains the usual NetBackup
backup image information.

The NetBackup catalog holds the information for all backups.  The deduplication mini-catalog holds backup information related to the images that are stored on MSDP.  When data is sent to MSDP, entries in the MSDP catalog are created to hold information about that data.  This data is different than the informaiton stored in the NetBackup catalog, though.

Actually, it's the "spad" service that manages the mini-catalog within MSDP, not the PostgreSQL database service.
