Probably becuase there is no 13th month so 01.13.03 can only be interpreted as
the 13th of January. Whereas your settings are probably such that 13.01.03 is
interpreted correctly as the 13th of January.
Well, it's that or the 01.13.03 is correctly interpreted and the 13.01.03 can
only be interpreted as the 13th as there is no 13th month.
Find out which it is by doing:
SELECT '02.01.03'::date
and checking your DATE STYLE setting. I'm not sure without looking what the
variable is that controls the interpretation of input but DATE STYLE is
probably a good point to start looking from.
Interestingly, doing the above select on my 7.3 doesn't show the time portion,
presumably you're using something older.
