I don't understand how a "real" company, even in todays overheated environment of soon-to-fail hipster startups, doesn't do (at least) one of these two things: a) have competent employees on staff that are intimately familiar with their critical infrastructure and how to support it or b) pay, yes, gasp, pay some other company for professional support services. A glance at the Wikipedia entry for Postgres shows some possible companies that do that. Or, as already mentioned, there are mailing lists.
But twitter? Really? That's support? For someone other than a hobbyist running a website in their spare time?
Go ahead, flame me. But my first impression is "amateur hour". My apologies if dribbble.com really is an amateur effort.
