Postgres - database backup

4 points
Created by:

In this short article, we would like to show how to make Postgres database backup from the command line under Linux. 

Quick solution:

pg_dump -h localhost -p 5432 -U my-username -W my-database > /path/to/backup.sql

Note: command will ask us to type the current username password.


To include SQL commands to clean (drop) databases before recreating them, use the following command (-c parameter):

pg_dump -c -h localhost -p 5432 -U my-username -W my-database > /path/to/backup.sql


  • -c┬ácauses adding clean queries on the database to the generated dump,
  • localhost┬áand┬á5432┬áshould be used according to┬áPostgres┬áserver address (host and port),
  • my-username┬áshould be replaced with current database credentials,
  • -W┬ácauses displaying propmpt to type the password for my-username,
  • my-database┬áindicates the name of the database that we want to copy,
  • /path/to/backup.sql should be replaced with destinated backup file location.
Note: do not forget to check if Postgres is installed or run the installation command:
sudo apt install postgresql postgresql-contrib - for Debian / Ubuntu Linuxes
