This has bitten me a couple times. In what version did it change?
My feeling, and I'd like to see what everyone else thinks, is that if you do not specify a locale, you get "C."
I think that initdb should default to something, and do the following:
* Have an explicit warnign if no locale specified, and what it is defaulting to
* Same for encoding. NO-ONE knows about the -E option when they first use postgres. Trust me on this.
* Same for -W. NO-ONE knows this exists. Then they change their trusts to md5 and they can't login to their postgres account anymore.
