Hello Chetan,
Here is how to compress PostgresSQL
FM Server is running slow with Postgres.
Please check database size ($INSTALLDIR/dcm/db/data), size should be less than 3 GB. (On windows, right-mouse click on “data” folder and select “properties” menu item, a dialog will pop up and display folder size. On linux/solaris, just run “du –k $INSTALLDIR/dcm/db/data.” command)
Run the following command to reduce size:
1.Stop FMServer.
      2. cd $POSTGRES_DIR/bin
      3. run ./psql.exe –U db_username dcmdb (where dcmdb is the database name)
      4.run this command at psql prompt.
                #vacuum full analyze verbose;
                #\q
      5. You should see database size is reduced. (The above might take a while)
Change the following parameter inpostgresql.conf to slow down the growth. Here is the instruction:
1. stop postgresql services
      2. edit $INSTALLDIR/db/data/postgresql.conf
      Change following parameter:
      checkpoint_segments = 6        
      max_fsm_pages = 532000
shared_buffers = 128MB
temp_buffers = 32MB
work_mem = 4MB
maintenance_work_mem = 16MB
max_fsm_pages = 532000
log_min_duration_statement = 200
      3. Restart postgresql services. (remove first '#' if it is there)
