About

PUM (PostgreSQL Upgrades Manager) is a robust database migration management tool designed to streamline the process of managing PostgreSQL database upgrades. Inspired by tools like FlywayDB and Liquibase, PUM leverages metadata tables to ensure seamless database versioning and migration.

Key Features

• Flexible Database Connections: Connect using PostgreSQL service names or direct connection strings (URI or parameters).
• Command-line and Python Integration: Use PUM as a standalone CLI tool or integrate it into your Python project.
• Database Versioning: Automatically manage database versioning with a metadata table.
• Changelog Management: Apply and track SQL delta files for database upgrades.
• Droppable & recreatable app with data isolation: PUM supports a clean rebuild workflow where an application environment can be dropped and recreated deterministically using hooks (pre and post migration).

Why PUM?

Managing database migrations in a Version Control System (VCS) can be challenging, especially for production databases. PUM simplifies this process by embedding version metadata directly into the database, enabling efficient tracking and application of migrations.

PUM was developed to address challenges in the TEKSI project, an open-source GIS for network management based on QGIS.
