As you were. Above worked for me as well. It appears to be a problem
with pgAdmin.

-- Returns nothing
SELECT a
FROM (
  select array_agg(a) a  from f
) s

-- Works
SELECT a
FROM (
  select array_agg(a) a  from f
  WHERE a < 12000
) s

-- Returns nothing
SELECT a
FROM (
  select array_agg(a) a  from f
  WHERE a < 13000
) s

When I ran in different client all queries returned results.
