Yeah, it's my fault.  Here in SF we're never sure what year it is, so we put
the year first.   <grin>

Really easy, actually:
SELECT to_char(datefield, 'MM-DD-YYYY');

That's the price you pay for having "real" dates instead of the delimited
string stored by other, less sophisticated, database systems.

One of the things on my todo list (Item #18, though) is a pl/perl function
that will accept any reasonable US date and return ISO standard for insert;
I'll post it to the list when I'm done (maybe next week).
