I'd go with PostgreSQL, takes 30-35 MB of RAM for one running connection. The entire stack (db + httpd + ruby/python/php) should take less than 150 MB. You have another ~ 300 in the prior model B.
Go should be faster and more efficient than python/ruby so I'd expect even less RAM/better performance.
SQLite3 these days is good for embedded devices but that's about it IMHO.
