Postgres update multiple rows based on multiple conditions in single query

When you need to update multiple rows based on multiple conditions, ever wonder if that can be done in a single query?

Here is a solution:

update account 
set currency = nv.currency
from
    ( values
        (12, 'EURO'),
        (18, 'DOLLAR'),
        (13, 'Pound')
    ) as nv (id, currency)
where account.id = nv.id ;
