I was wondering about the datestyle in postgresql.

As i am from europe, i like the datestyle setting:


Now i was under the impression i just had to execute the command once on the db.. and i'd be ok for the rest of my life....

But to my surprise everytime i reconnect to the db using pgAdminIII (god i love that tool) i have to set the datestyle.

Is there a switch i missed in postgres.conf?
I'd hate to think i have to include the datestyle for every page, query that connects to the db..
