Tom,

So the closest approximation to the default "postgres[ql]" date style
of MM-DD-YYYY (note delimiters) is: SQL,US which returns a
MM/DD/YYYY 00:00:00 value when doing some date arithmetic?

Have I got it right?  Egads...in addition to calling substr() to lose
the 00:00:00 (not terribly useful in this context)  I'll have to
call perl's binding operator (=~) to swap in hyphens as delimiters.

Bottom line: there is no way to return a MM-DD-YYYY value?

I never realised that the morphology of the traditional Postgres date
was this complex (its declension was not apparent until I used the
INTERVAL keyword) and so I've conditioned my users to using hyphens
as delimiters...argh.  Should have used slashes I suppose.

Oh well.  Thanks for the help.
