Description:

Issue While passing null as value during procedure/Function Call from
Groovy.
We have a below Procedure in Postgresql

CREATE OR REPLACE PROCEDURE schemaname.procedurename(
INOUT out_ctid integer DEFAULT NULL::integer,
in_ctname character varying DEFAULT NULL::character varying,
in_address1 character varying DEFAULT NULL::character varying,
in_address2 character varying DEFAULT NULL::character varying,
in_address3 character varying DEFAULT NULL::character varying,
in_address4 character varying DEFAULT NULL::character varying)
LANGUAGE 'plpgsql'
AS $BODY$
BEGIN
INSERT INTO schemaname.tablename (ctid_new, ctname, address1, address2,
address3, address4)
VALUES (nextval('schemaname.ct_sq'), in_ctname, in_address1,
in_address2, in_address3, in_address4,);
out_ctid := currval('schemaname.ct_sq');
END;
$BODY$;

We are facing Calling this procedure from Groovy ( using
postgresql-42.2.14.jar and also replaced with latest jar -
postgresql-42.2.18.jar)

Below is our calling statement
sql.call("call
schemaname.procedurename(${​​​​​​​​Sql.INTEGER}​​​​​​​​,$ctName,$address1,$address2,$address3,$address4)")
//values of all address variables are null

we are getting the below error

SQL Exception: ERROR: procedure schemaname.procedurename(character varying,
unknown, unknown, unknown, unknown) does not exist
