Best 9 Postgres Database Migration Tools For 2024

Have you considered moving to PostgreSQL yet? Do you need to know what you should do?

If you need to lower your expenses, optimize speed, or avoid vendor lock-in, PostgreSQL offers excellent open-source database solutions. However, the whole conversion might appear scary. Luckily, there are necessary tools that can improve our lives. 

In this blog, we’ll look at some of the best Postgres database migration tools. These tools can streamline the migration process, simplify data transfer, minimize downtime, and ensure data integrity.

What is PostgreSQL?

PostgreSQL is a database system capable of object-relational handling; it is free of charge and open source. PostgreSQL has earned a reputation for its solid architecture, interoperability with other applications through SQL standards adherence, high degree of usefulness regarding data integrity, and rich feature set.

Regarding data types, PostgreSQL supports the likes of primitive datatypes such as integers or strings, structured datatypes such as array or date-time, or Documents such as JSON/JSONB and XML, and even allows you to define your data types and build custom functions in multiple programming languages.

Why migrate to PostgreSQL?

Thinking about making the switch to PostgreSQL? Here’s why it might be the perfect choice for you and your business:

• Cost of Implementation: PostgreSQL is an open-source DBMS that is free to use, download, and distribute. By choosing PostgreSQL, you can save a ton on software costs and even reduce hardware expenses.
• Ease of Implementation: Implementing PostgreSQL is effortless thanks to its straightforward architecture and modular design. It has separate modules for functionalities like replication, backup, and high availability, allowing you to pick what’s relevant to your use case. This reduces complexity and makes it much easier to get up and running. Tools like pgAdmin offer a user-friendly interface that even beginners can navigate easily, so you don’t need specialized skills to manage your database.
• Scalability: PostgreSQL scales impressively well, handling up to 100,000 transactions per second (TPS) on a single server. This makes it a solid choice for large-scale applications that demand high throughput.
• Performance: You’ll love PostgreSQL’s performance, with its low latency and high throughput, ensuring your applications run smoothly and efficiently.

2. pg_chameleon

pg_chameleon is a tool for quickly performing replication from MySQL into PostgreSQL. It was developed using Python 3.5+. It employs mysql-replication to capture row images of MySQL databases. The images are converted into a JSONB data structure. A pl/pgsql function decodes the JSONB, replaying your changes directly into your PostgreSQL database.

Founded: 2016

Features

• Compatibility: If you’re working with multiple MySQL schemas within the same cluster and want to replicate them into a PostgreSQL database, pg_chameleon has you covered. You can even use different names for the source and target schemas, giving you flexibility in your setup.
• Error Handling: pg_chameleon takes a conservative approach to replication. If any table generates errors, it gets automatically excluded from the replica, so you don’t have to worry about messy interruptions. pg_chameleon can also integrate with Rollbar, making error detection and alerting easy. 
• Schema Management: pg_chameleon also comes with daemonized processes for init_replica, refresh_schema, and sync_tables, as well as a replica process that runs two separate subprocesses—one for reading and one for replaying data.
• Data Consistency: Soft replica initialization, where tables are only locked when needed and stored with their log coordinates, ensures the database gradually reaches a consistent state.

Pricing
