📝 Tech Blog: Solving the "input file appears to be a text format dump. Please use psql" Error with psql

Hey there tech enthusiasts! Today, let's dive into a common issue that many developers face while importing a PostgreSQL backup file. If you've received the error message "input file appears to be a text format dump. Please use psql," stick around because we've got the solution for you! 🛠️

Now, let's look at the scenario. You've taken a backup of your production database using the command:

pg_dump db_production > postgres_db.dump

And then, you've copied the backup file to your local machine using the "scp" command. But when you try to import the dump file into your local development database using the following command:

pg_restore -d db_development postgres_db.dump

Bam! You encounter the dreaded error:

pg_restore: [archiver] input file appears to be a text format dump. Please use psql.

Don't you worry, my friend! We've got an easy solution, and it involves our trusty friend, psql. Let's get started! 🎉

Understanding the Problem

So, why is this error being thrown at you in the first place? Well, when you dump a PostgreSQL database using the pg_dump command, it generates a text file containing the SQL statements necessary to recreate the database. However, the pg_restore command expects to work with a binary format dump file. Hence, the error!

The Solution: Using psql to Import the Dump File

To fix this, we need to use the psql command instead of pg_restore. Let's rewrite our import command:

psql -d db_development -f postgres_db.dump

Ta-da! By using psql -d db_development -f postgres_db.dump, you can successfully import the dump file into your local development database without any errors. 🚀

A Word of Caution

Keep in mind that using psql -d db_development -f postgres_db.dump will execute all the SQL statements from the dump file directly. So, if you had any existing data in your local development database, it will be replaced.
