Cleaning pg_log should be enough to be able to start your postgres instance. However, it will let you with almost no space for your database to grow. If you have some tables with information you can delete, that can free up space. Unless most of your database information is "volatile"(case in which you should implement an automatic cleanup cron), the only remaining option is to get a larger disk for your vps.

Maybe your "pg_log" folder has some space to free. If that doesn't helps, you may need to forcefully add more space. There's not really much alternatives there.
