SELECT counts

Hello all,

I have a table with id and status_v.

create table myt (id integer, status_v varchar(10));
insert into myt values (1,'I');
insert into myt values (1,'P');
insert into myt values (1,'T');
insert into myt values (2,'P');

User gets counts of status records, filtered on some status_v like this
test=# select count(*), status_v from myt  where status_v in ('I','P','X')

group by status_v;
 count | status_v
-------+----------
     1 | I
     2 | P
(2 rows)

Is there a way in which I can have the output as
     1 | I
     2 | P
     0 | X

i.e., if there is not data, the count should be displayed as 0.

Regards,
Jayadevan
