Hi,
Please look at my query :
[shreyas@rails_app_test (master)]$ rails db
psql (9.4.1)
Type "help" for help.
app_development=# select id, location, name from people;
id | location | name
----+----------+------
2 | X | foo
3 | X | foo
4 | Y | foo
(3 rows)
app_development=# SELECT COUNT(id) FILTER(WHERE lower(location) != 'x') AS
Non_X_loc, COUNT(id) FILTER (WHERE lower(location) = 'x') AS X_loc FROM
"people";
non_x_loc | x_loc
-----------+-------
1 | 2
(1 row)
This *FILTER* method is available from 9.4, How can I get the same output below
9.4 version ?

Debugging is twice as hard as writing the code in the first place. Therefore,
if you write the code as cleverly as possible, you are, by definition, not
smart enough to debug it.
