[Zope-DB] Localised date format

[Charlie Clark]

Dear list,

I can't seem to be able to convince Zope to use DateStyle German in 
PostgreSQL
SET DateStyle to German;
works fine in psql but is a runtime condition and I don't seem to be able 
to set it from within Zope.
The alternative of using to_char(my_date, 'DD.MM.YYYY') seems to be very 
resource intensive.

Is there a way of making DateSytle German permanent? and doing this from 
within Zope?

Thanx

Charlie
