Backup a Single PostgreSQL Database

PostgreSQL provides the pg_dump utility to help you back up databases. It generates a database file with SQL commands in a format that can be easily restored in the future.

To back up, a PostgreSQL database, start by logging into your database server, then switch to the Postgres user account, and run pg_dump as follows (replace tecmintdb with the name of the database you want to backup). By default, the output format is a plain-text SQL script file.
