I'd like to issue a query that lists all the rows of a table whose 'date'
columns(its type is datetime) is falls in a month, i.e. these rows were
inserted in , say August. How can I do that?

 When I bugged with that problem I found an interesting bug:
elmu=> select date_trunc('month','now'::datetime);
date_trunc
-----------------------------
Thu Oct 01 00:00:00 1998 CEST
(1 row)

That's OK.

elmu=> select date_trunc('month','now'::datetime) + timespan('1
month'::reltime)
;
?column?
----------------------------
Sat Oct 31 23:00:00 1998 CET
(1 row)

Why not Nov 1?

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
