## What it is
Migra is a schema diff tool for PostgreSQL, written in Python, that compares two database schemas and autogenerates the SQL migration statements needed to get from one to the other. The project is officially deprecated; its functionality continues in the successor project 'results'.

## Use cases
- diff two postgresql schemas
- autogenerate sql migration scripts from schema changes
- sync development database schema with application models
- make database schema changes testable and automatic

## When to choose
- you need a schema diff for PostgreSQL and are okay using an unmaintained tool
- you want to explore its approach before trying the successor project

## When to avoid
- you need maintained software with ongoing bug fixes and releases
- you use databases other than PostgreSQL
- you want long-term support - use the successor project 'results' instead
