Is there a batch/bulk UPDATE syntax available?

Hi,

Is there a batch/bulk UPDATE query syntax available in PostgreSQL, similar
to multirow VALUES syntax available for INSERT?

INSERT Multirow VALUES syntax example:
INSERT INTO films (code, title, did, date_prod, kind) VALUES
    ('B6717', 'Tampopo', 110, '1985-02-10', 'Comedy'),
    ('HG120', 'The Dinner Game', 140, DEFAULT, 'Comedy');

There is a situation in my application, where I am performing lots and lots
of updates on individual rows. I am trying to figure out how to make the
updates faster.

Any other ideas/ways to make updates faster are highly appreciated.

Regards,
Gnanam
