PostgreSQL's version involves UPDATE ... FROM. Use an ORDER BY in the
FROM clause like this:
UPDATE mydemo SET cat_order = m.cat_order+1
FROM (
SELECT cat_order, client_id
FROM mydemo
WHERE
client_id = 1 AND
cat_order >= 0
ORDER BY cat_order) m
WHERE
mydemo.cat_order = m.cat_order AND
mydemo.client_id = m.client_id
More details on PostgreSQL's UPDATE are at:

David.
