This command is used to perform a database backup using the pg_dump utility in PostgreSQL. Here is a breakdown of the command:

pg_dump: This is the command-line utility used to create a backup of a PostgreSQL database.
-U ${username}: This option specifies the username to connect to the database. ${username} is a placeholder that should be replaced with the actual username.
${db_name}: This is the name of the database to be backed up. ${db_name} is a placeholder that should be replaced with the actual database name.
> ${output_file.sql}: The > symbol is used for output redirection, indicating that the output of the pg_dump command should be redirected to a file instead of being displayed in the console. ${output_file.sql} is a placeholder that should be replaced with the desired name and location of the backup file. The file extension .sql is commonly used to indicate that it is a SQL script.

In summary, this command connects to a PostgreSQL database with a specific username, performs a backup of the specified database, and saves the backup to a designated output file in SQL format.
