If you can do this one without unnesting the downloads array I do not know how. Having done that: (WHERE dlarray->'publd' = '123) I think it’s doable like this: select * from contacts where data @> '{"downloads":[{"pubid":123}]}'::jsonb …which would be aided by a gin index on ‘data’ using jsonb_path_ops: CREATE INDEX idx_data_path_ops on contacts USING gin (data jsonb_path_ops); https://www.postgresql.org/docs/10/static/datatype-json.html#JSON-INDEXING Best, Steve.
