postgresql - Processing record type from a jsonb_each query -


i store data json. want flatten data using jsonb_each. new column type record, don't how extract values it.

select t (   select json_each_text(skills::json->'prizes') users) t;

the output is

        jsonb_each             --------------------------------- (compliance,2) (incentives,3) (compliance,0) (legal,3) (legal,2) (international-contributions,3)

the type record.

pg_typeof  ----------- record

i want aggregate , groupby, cannot figure out how extract first element(the string) , second element (the value).

here workaround have found: json -> row -> json -> (string, integer) , aggregate. wondering if there shortcut , skip row->json conversion.

select u.key, avg(u.value::int)   (select   row_to_json(t)->'s'->>'key' key,   row_to_json(t)->'s'->>'value' value       (select jsonb_each(skills::jsonb->'prizes') s     users) t     ) u group key;
