Hi All,

We are using pg_dump backup utility in order to take the backup of the database. Unfortunately,it is taking around 24hrs of time  to take the backup of  28GB database. Please guide me how to reduce the time and is there any parameter need to be modified which will help us to reduce the backup time. We are using Postgres 9.2 version

Note:-Kindly suggest me options using pg_dump only.
