Export MySQL Database to PostgreSQL

Introduction to pgLoader

pgLoader is an open-source tool designed for migrating databases from MySQL to PostgreSQL efficiently. It supports secure migrations using SSL connections and can perform a migration with a single command.

Installing pgLoader

To use pgLoader's useSSL option, install pgLoader from source. It is available in the default Ubuntu APT repositories but requires manual installation for SSL support.

Preparing SSL Certificates

pgLoader requires trusted SSL certificates for connecting to MySQL. Copy the ca.pem and client-cert.pem files to the /usr/local/share/ca-certificates/ directory, rename them with a .crt extension, and update the certificate store using the update-ca-certificates command.

Creating a MySQL User

Create a dedicated MySQL user with access to the MySQL database from the Postgres machine. This user will be used by pgLoader to initiate the migration over an SSL connection.

Backup with mysqldump

Before migration, use mysqldump to back up your MySQL database. Although pgLoader does not alter data, backing up is a precautionary step.

Executing Migration

Run pgLoader with the appropriate connection strings for the source MySQL database and the target PostgreSQL database. Include SSL options to ensure a secure migration process.

Verification

After migration, verify the data in the PostgreSQL database by running a query to check that the data has been correctly migrated.

Conclusion

Using pgLoader, export your MySQL database to PostgreSQL with ease, taking advantage of its ability to migrate an entire database securely and efficiently.

Frequently Asked Questions

What tool can be used to export a MySQL database to a PostgreSQL database?

pgLoader, an open-source database migration tool, can be used to export a MySQL database to a PostgreSQL database.

Does pgLoader support SSL connections for MySQL?

Yes, pgLoader requires trusted certificates for SSL connections to MySQL and uses the useSSL option in the MySQL connection string to connect over SSL.

Can pgLoader be used to migrate a MySQL database to a managed PostgreSQL database like DigitalOcean's?

Yes, pgLoader can migrate a database from a self-managed database to a managed PostgreSQL database, such as those available through DigitalOcean.

How does pgLoader handle the data during migration?

pgLoader does not delete or transform data; it only copies the data from the source database to the target database.

What is required to connect pgLoader to a managed PostgreSQL database?

To connect pgLoader to a managed PostgreSQL database, the sslmode=require option is required.
