Restore a postgres backup file using the command line?

📝 Tech Blog - Super Easy PostgreSQL Backup Restore using Command Line

Hey there tech lovers! Today, we're diving into the world of PostgreSQL database backups and how to restore them using the command line. 🗄️💻

So, you've created a backup of your PostgreSQL database and now you're wondering how to restore it on a remote server without the luxury of a GUI like pgadmin3? Fear not! We've got you covered with some super easy solutions. 🚀

The GUI Problem 😕

You mentioned that you're using pgadmin3 locally but don't have the same luxury on the remote server. While pgadmin3 is a fantastic GUI tool, sometimes we don't always have that luxury in every situation. But fear not, the command line has your back! 👊

Solution 1: Using pg_restore 🔄

The pg_restore command is your knight in shining armor when it comes to restoring PostgreSQL backups from the command line. Let's break down the process step by step: 🔍

1. First things first, make sure you have a backup file ready to go. You mentioned that you've already copied it over to the remote server. Excellent! 💪

2. Open up your trusty command line interface and navigate to the directory where your backup file resides.

3. Run the following command, replacing [backup_file] with the actual name of your backup file:

pg_restore -U [username] -d [database_name] [backup_file]

• The -U flag specifies the username for connection.

• The -d flag specifies the target database you want to restore.

• And [backup_file] is the name of your backup file.

For example, if your username is myuser, your database is called mydatabase, and your backup file is backup.sql, the command would look like this:

pg_restore -U myuser -d mydatabase backup.sql

1. Sit back and relax while PostgreSQL works its magic! Your backup will be restored to the specified database in no time. 🌟

Solution 2: Using psql 🐘

If pg_restore isn't your cup of tea or you want to try a different approach, you can also use the psql command to restore your PostgreSQL backup file. Here's how:

1. Once again, make sure you have your backup file ready to go.

2. Open your command line interface and navigate to the directory where the backup file is located.

3. Run the following command, replacing [username] and [database_name] with your actual credentials, and [backup_file] with the name of your backup file:

psql -U [username] [database_name] < [backup_file]

• The -U flag specifies the username for connection.

• The [database_name] is the target database for the restore.

• And [backup_file] is the name of your backup file.

For example, if your username is myuser, your database is called mydatabase, and your backup file is backup.sql, the command would look like this:

psql -U myuser mydatabase < backup.sql

1. Grab a cup of coffee, and let PostgreSQL do its thing! Your backup will be restored in a jiffy. ☕🌈
