The only way to determine if there are messages or not is to query the database and determine if there are messages. There's no magic mechanism here. However, there are other message backends that don't require database access. Django ships with a cookie-backed messages engine. Since the message storage is a pluggable interface, it's also possible to build a messages backend that stores in memcache, redis, or some other non-database store. These don't require database access because they don't store messages in the database. Whether they will work for your situation is entirely up to your requirements.
