Setting datestyle variable has effect only for the session it was issued
in. It was made so to avoid interfernce with another sessions since
they could be started not only by you, but someone else (remember --
PostgreSQL is multiusear). So, the solution is to run postmaster with
"-e" turned on to get the datestyle you need by default-- for details
check manpages postmaster(1) and postgres(1).
