I've been bitten by this too. It seems that there are two
characteristics for the dates: format (for output) and 'conventions' for
input, and that 6.5 -> 7.0 changed from defaulting to European
conventions to US conventions.

I suspect this is Debian specific.

Perhaps there should be a way of setting the conventions side of things
in the /etc/postgresql/postmaster.init like there is a way of setting
the format?
