pg_dump:tldr:e06f3

This command is a PostgreSQL database utility command called "pg_dump" that is used to create a backup of a PostgreSQL database. Here's a breakdown of the command:

• pg_dump is the actual command that performs the backup operation.
• -a is an option used with pg_dump to specify that only table data should be backed up, excluding the database schema and settings.
• ${db_name} is a placeholder that should be replaced with the actual name of the database you want to backup. For example, if your database is named "mydatabase", you would replace ${db_name} with mydatabase.
• > is the output redirection operator. It redirects the output of the pg_dump command to a file instead of displaying it on the console.
• ${path-to-output_file-sql} is a placeholder that should be replaced with the actual path and filename where you want to save the backup file. For example, if you want to save the backup file as "/home/user/backup.sql", you would replace ${path-to-output_file-sql} with /home/user/backup.sql.

Overall, this command will create a backup file containing the table data of the specified PostgreSQL database and save it at the specified location.
