Add option to add function to DB trusted sources

The solution Digital Ocean suggests, is what makes the Serverless product mostly unusable for any production use case. You basically are left with 2 choices:

1. Use functions, deploy them yourself, there you have the option to disable the http traffic and add triggers, but you are basically not allowed to connect to the db due to trusted sources restriction, which basically makes it useless
2. Deploy a Starter App that has functions, expose your function to the public, have no triggers for functions, which is also useless and even more dangerous due to the public traffic being open, even if there is webSecure.

Can we get an option that actually makes sense from the production stand point. I feel like every Saas product except for droplets, has to be crippled in its own way so that it's essentially unusable.
