## What it is
A Python script that converts MySQL database dumps into PostgreSQL-compatible SQL, originally built for Lanyrd's migration from MySQL to PostgreSQL. It works on mysqldump output generated with PostgreSQL-compatible flags and produces a loadable PostgreSQL dump.

## Use cases
- convert mysql database to postgresql
- migrate from mysql to postgres
- convert mysqldump output to psql-compatible sql
- one-off database migration script for django projects
- load mysql data into a fresh postgres database

## When to choose
- you need a quick, scriptable one-shot MySQL-to-PostgreSQL conversion
- your schema is Django-based and simple column-type mapping is acceptable
- you want a lightweight tool rather than a full migration service

## When to avoid
- you need ongoing replication or live sync between MySQL and PostgreSQL
- your schema has complex types or needs careful, tunable conversion
- you need an actively maintained tool - this was built for one specific database and is largely unmaintained

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: etl, database, cli
- domain: databases, developer-tools
- platform: python, cli
