I want to obtain current week number.
Under PHP I try:

$query = "SELECT EXTRACT(WEEK FROM NOW)";
$result= pg_exec($dbconn,$query);

select date_part('week', CURRENT_TIMESTAMP);

Both

SELECT extract(week FROM now());

and

SELECT extract(week FROM CURRENT_TIMESTAMP);

work as expected. I don't know which is the *accepted* SQL 92
idiom, but I would bet that it isn't 'now().'

In 7.1.x, try:

SELECT EXTRACT (WEEK FROM CURRENT_DATE);

in older postgres maybe this:

SELECT EXTRACT (WEEK FROM DATE 'today');

I'll just point out that using date_part isn't ANSI SQL, you should use the
EXTRACT function, and the CURRENT_DATE, CURRENT_TIME and CURRENT_TIMESTAMP
variables.
