sql - Advanced hstore with postgresql -

-

in ruby on rails application have sql retrieve advanced data , convert sql output hash , update proper model record. in sql have line one:

hstore(array_agg('some_key'::text), array_agg('some_value'::text))  loaded_user_data

which after converting hash returns me:

 "loaded_user_data"=>"\"some_key\"=>\"some_value\""

but problem want have hash looks little bit different. example:

 loaded_user_data: {     loaded: { count:  100, details: [] },     failed: { count: 2, details: ['duplicate', 'invalid_external_id']},     invalidated: {count: 1, details: ['requested client']}  }

is there way hstore?
