Banco de dados do WordPress sob controle de versão

Fiz um scriptzinho maroto pra manejar o dump de um banco de dados do WordPress. Ele serve pra exportar os dados do banco para um arquivo texto, substituindo a URL do site por uma string mágica; e também pra importar os dados do arquivo texto para o banco, desfazendo a substituição da URL. Assim, a gente consegue manter os dados do servidor de homologação/produção sob controle de versão, exportando estes dados para o arquivo texto sempre que há modificações no servidor, e importando os dados nas máquinas de desenvolvimento, mantendo o conteúdo do servidor replicado na máquina do desenvolvedor. Deu pra entender? Espero que não.
