Schema.db dump to MySQL.sql?

Currently I have my development & test environments configured under
PostgreSQL, but I want to do some cross compatibility tests and need to
export the schema.db structure and test fixtures into a MySQL compatible
dump file to be able to perform some raw SQL queries on the data to
it validates.

How can I do this?
