Converting some MySQL code to work with Postgres here.
I have this query:
SELECT
tasks.task_id,
(tasks.task_duration * tasks.task_duration_type /
count(user_tasks.task_id)) as hours_allocated
FROM tasks
LEFT JOIN user_tasks
ON tasks.task_id = user_tasks.task_id
WHERE tasks.task_milestone =
Add :
AND count(user_tasks.task_id) 0 in the where clause.

Maybe try something like this :
SELECT
task_id,
CASE
WHEN task_count = '0'
THEN '0'::int4
ELSE (task_duration *
task_duration_type /
task_count) as hours_allocated
END
FROM
(SELECT
task_id,
task_duration,
task_duration_type,
count(user_tasks.task_id) as task_count

Try HAVING then.

You need to put it in HAVING, instead.
Note also this
