Or (in 7.0):
SELECT datums FROM jaunum WHERE to_c
This is not exactly what the original question was about. You select the month
is one specific year only.
What you do it however easier achieved by:
SELECT datums FROM jaunumi WHERE date_trunc('month', datums) = '2000-08-01';
datetime is an type full of tricks. :-)

Where datums is a timestamp field.

Actually, PostgreSQL has specific function for this purpose. The query would
be:
SELECT * FROM table WHERE date_part('month', date_field) = '8';
(example to select month 8)
If you use date_trunc, the selection will be by month/year - that is,
date_trunc('month', date_field) will always result
This might seem rather silly, but could you simply do something like:
select * from database
where date_field >= '01/01/2000'::date
and date_field < '02/01/2000'::date;
Of course, if date_field could contain many different years, then this
would not get you the result you wanted.
