I'd use mysqldump to create 2 files: the first being the schema, which I'd tweak to suit ( implementing tablespaces for example ), and then a second dump, which exports the data in a format that is acceptable to postgres.

That way, you end up with what you want in a simple, repeatable manner.

If it's mysql 5 then the stored procedures may need to be converted - I know there are tools out there, but haven't used them and can't comment.
