Migrating MySQL to PostgreSQL

Migrating MySQL to PostgreSQL

When I started writing pg_chameleon I had in mind a tool making simple to migrate from different dbms engines to PostgreSQL. The name was inspired by the Culture Club’s Karma chameleon song which suggested me the idea of a tool capable to move data between different database technologies. Then tool’s scope changed becoming a replica system rather a migration system but I’ve kept the name as I think the idea is still valid.
