Re: Re: Database Name Case Sensitivity

I am sure it is a Good Thing, thank you for the explanation. I will just
have to change my thinking to all lowercase and get used to it.

Sort of on the same topic, does anyone know of a PostgreSQL primer for those
making the change from MySQL. Changing religions :} is never easy,
something to ease the transition and point out the differences and gotchas
would be very helpful.

Thanks for the help,
Brian
