Re: cant get what I want from array_to_json (simple)

CREATE TYPE key_value_pair AS

   (key text,

    value text);

DO $$declare

   arr qsn_app.key_value_pair[]; 

   pcolumn_values_i json;

begin

  arr[0]  := ('this','that');

  arr[1]  := ('another','one');

  pcolumn_values_i := array_to_json( arr );

  RAISE NOTICE '#1 %', pcolumn_values_i;

end$$;

the 'NOTICE' shows:

NOTICE:  #1 [{"key":"this","value":"that"},{"key":"another","value":"one"}]

what I want to see is:

NOTICE:  #1 {"this":"that","another":"one"}
