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.
