Thanks.
Another problem. I issued the following query:
select * from annex_log where login_start
    between
    (select date_trunc('month','now'::datetime)) and
    (select date_trunc('month','now'::datetime)) +
    timespan('1 month'::reltime);

but postgresql said there's a parse error near select
while the following query did work

select * from annex_log where login_start >=
    (select date_trunc('month','now'::datetime)) and login_start <
    (select date_trunc('month','now'::datetime) +
    timespan('1 month'::reltime));

Why?

Sebestyén Zoltán AKA Memphisto        It all seems so stupid,
                    it makes me want to give up.
szoli@neumann.cs.elte.hu        But why should I give up,
                                        when it all seems so stupid?

MAKE INSTALL NOT WAR            And please avoid Necrosoft Widows
