Postgres Data Migration Tools - Featured Image

Enterprises need to move their data from one source to another for several reasons. They might need to move data while upgrading their databases, establishing a new data warehouse, etc. Whenever there is a requirement for migrating data, most developers, DBAs (database administrators), and enterprise owners seek an automated solution.

There are several kinds of migrations. You can migrate from one technology to another, to a new data center or cloud, or even to another computer in the exact location and technology.

The ideal for a Postgres Database Migration tool relies on the type of migration and needs, such as availability or downtime tolerance. Therefore it might be challenging to discover the appropriate tool for the job.

This article outlines some of the most efficient and user-friendly Postgres Database Migration tools to explore before opting for one.

What is PostgreSQL?

PostgreSQL is a powerful database management system compliant with relational and non-relational queries. Several data warehouses, including AWS Redshift, are based on PostgreSQL as it has several features to store and scale complicated data workloads. With more than 30 years of development on core platforms, it has earned recognition for its architecture, data integrity, reliability, and extensibility. 

PostgreSQL runs on all operating systems with powerful add-ons like PostGIS, a geospatial database extender. It is highly extensible with defined APIs for many features; you can define your data types, build custom functions, and even write code in different programming languages.

Scale your data integration effortlessly with Hevo’s Fault-Tolerant No Code Data Pipeline

As the ability of businesses to collect data explodes, data teams have a crucial role to play in fueling data-driven decisions. Yet, they struggle to consolidate the data scattered across sources into their warehouse to build a single source of truth. Broken pipelines, data quality issues, bugs and errors, and lack of control and visibility over the data flow make data integration a nightmare.

1000+ data teams rely on Hevo’s Data Pipeline Platform to integrate data from over 150+ sources in a matter of minutes. Billions of data events from sources as varied as SaaS apps, Databases, File Storage, and Streaming sources can be replicated in near real-time with Hevo’s fault-tolerant architecture. What’s more – Hevo puts complete control in the hands of data teams with intuitive dashboards for pipeline monitoring, auto-schema management, and custom ingestion/loading schedules. 

All of this combined with transparent pricing and 24×7 support, makes us the most loved data pipeline software on review sites.

Postgres Database Migration Tools

The following are the 9 significant Postgres Database Migration Tools:

1) pg_chameleon

pg_chameleon is a MySQL to PostgreSQL replication mechanism written in Python 3. It can connect to the MySQL replication protocol and replicate data changes in PostgreSQL. Whether the user has to set up a permanent replica between MySQL and PostgreSQL or execute an engine migration, pg chameleon is an excellent tool for the job.

The primary characteristics are as follows:

  • Read from several MySQL schemas and restore them into a PostgreSQL database of choice.
  • Configure PostgreSQL to serve as a MySQL slave.
  • Basic DDL (CREATE/DROP/ALTER TABLE, DROP PRIMARY KEY/TRUNCATE, RENAME) support
  • Error-producing tables are immediately omitted from the replica.
  • It is possible to refresh individual tables or schemas.
  • Remove the MySQL replica for migration assistance.
  • The init replica process was daemonized.
  • Daemonized replica process with two distinct subprocesses, one for reading and one for replaying

2) pgloader

pgloader loads data into PostgreSQL and enables Continuous Migration from your existing database to PostgreSQL. Continuous Migration makes it simple to make incremental progress over time and halt and continue migration activities later if necessary.

There are two ways to use pgloader. It can load data from files like CSV or Fixed-File Format or convert an entire database to PostgreSQL.

As a migration source, pgloader supports numerous RDBMS systems and retrieves information from catalog tables via a connection to construct an equivalent schema in PostgreSQL. This means you can switch to PostgreSQL with a single command!

3) Ora2pg

Ora2pg is a data migration tool to migrate data from Oracle to PostgreSQL. It is an open-source tool that scans and extracts the data and database schema to generate PostgreSQL-compatible scripts to populate the latter. You do not require any Oracle database knowledge besides providing the parameters to connect. 

The tool comprises two main components, a Perl script (ora2pg) and a Perl module (Ora2pg.pm). Once you set up Oracle as the source database, you must set the export type (TABLE / MVIEW / GRANT / PROCEDURE / INDEXES / TRIGGER, etc.). Ora2pg can also provide cost estimates for migrating PL/SQL code from files, generating ktr files in XML format for Pentaho Data Integrator (Kettle), and processing multiple SQL commands concurrently. 

Ora2pg is a no-cost tool for Postgres Database Migration Tool.

Fivetran is a data pipeline service provider that extracts source data and connects it to a cloud data store or warehouses built with PostgreSQL. It pulls data from multiple sources and moves it with a low-impact change data capture (CDC). Using the CDC technique, Fivetran reads logs of changes rather than sending queries about your data. These changes are then channelized to your output warehouse. 

Fivetran improves the accuracy of data-driven decision-making by synchronizing data, automating the in-warehouse transitions, and managing read-to-query schemas. Fivetran data pipeline levies approximately 99.9% platform uptime to indicate its reliability. The ETL tool claims to sync 1,000+ terabytes of data monthly. It is a better alternative to getting a whole data engineering team to load your data into PostgreSQL.

Fivetran offers several packages like Starter (US$ 120), Standard Select (US$ 60), Standard (US$ 180), Enterprise (US$ 240), and Business Critical pack (on-demand).
