new stored procedure with OUT parameters

[Anton Shen <4175george@xxxxxxxxx>]

Hi all,

I was playing around with the stored procedure support in v11 and found that pure OUT parameters are not supported. Is there any reason we only support INOUT but not OUT parameters?

psql (11.0 (Homebrew petere/postgresql))

dev=# CREATE PROCEDURE test_sp(a OUT int) LANGUAGE plpgsql AS $$

dev$# BEGIN

dev$# a = 5;

dev$# END; $$;

ERROR:  procedures cannot have OUT arguments

HINT:  INOUT arguments are permitted.

Thanks,

Anton
