将 PostgreSQL 函数转换为 PostgreSQL 存储过程

Question

I'm migrated a schema from oracle to postgreSQL using AWS-SCT, packages are converted to functions in postgreSQL. I need to convert this function to procedure to compact with the code in the application middleware.

I've tried to convert to procedure, everytime i'm getting error like SQL state: 42601 and inout parameter are permitted

Kindly help to convert the function to procedure.

CREATE OR REPLACE Function "pk_audfreq$sp_audfreq"(
    OUT out_a double precision,
    OUT out_b double precision,
    OUT out_c double precision)
    RETURNS record
    LANGUAGE 'plpgsql'
    COST 100
    VOLATILE 
AS $BODY$
DECLARE
BEGIN    
    SELECT
        MIN(audresponsetime), AVG(audresponsetime), MAX(audresponsetime)
        INTO STRICT out_a, out_b, out_c
        FROM public.audio_freq;        
    END;
$BODY$;

You cannot have OUT parameters with procedures (yet). As the documentation states:

OUT arguments are currently not supported for procedures. Use INOUT instead.
