No, you can't. You're contract should contain language regarding you
not being responsible for data loss, to protect you from jerks like this.

It's possible for any program to lose data, if the hardware fails, if the
user tries to edit files that they shouldn't. If the user has admin
access to the PostgreSQL box, they can cause data loss.

I've actually seen people accidentally hit "yes" twice when they didn't
want to. Tell him to lay off the coffee.

Yes. Call your lawyer first and see what the laws in your area say
regarding this. Then talk to your lawyer about making sure your
boilerplate contract covers this kind of thing and protects you from
future incidents. Take your lawyers advice on how to handle it.
In any event, refuse to ever do any business with him again. In my
experience, these kinds of customers aren't worth the pennies they pay
you. Also, refuse to give in. If you give him anything for free, he'll
never leave you alone. I have personal experience with these types.
I am not a lawyer ... I just play one on the Internet.
