Thread: Probs with int2 in functions

I'm using PostgreSQL v6.3.2.

It appears that the function command doesn't like the type "int2" as a
parm in a call. For example,

zedadmin=> \i zz.sql
create table test2(
  trk_id        int2            not null,
  trk_nm        varchar(30)     not null,
  trk_comp      varchar(30));
CREATE

create function insert_test2(int2,varchar,varchar)
returns int4 as
 'insert into test2
  values($1,$2,$3);
select 1 as return_val;'
language 'sql';
CREATE
EOF

The objects are successfully created, but when I come to insert data via
the function there is the following error.

zedadmin=> select insert_test2(1,'My name','My comment');
ERROR:  function insert_test2(int4, unknown, unknown) does not exist

If one changes the int2 to an int4 in the table and function, the function
is happy to insert the data into the table.

Any ideas why this is so, or is it a bug?

It works on my v6.4:

select insert_test2(1,'My name','My comment');
insert_test2
------------
           1
(1 row)

select * from test2;
trk_id|trk_nm |trk_comp
------+-------+----------
     1|My name|My comment
     1|My name|My comment
(2 rows)

Any way try to cast values as:
select insert_test2(1::int2,'My name'::varchar,'My comment'::varchar);

So it appear that it is a bug in 6.3.2!

I'd prefer not to do that. Also, since it isn't necessary for the int4
case then it shouldn't be for the int2 case and this suggests to me that
it is a bug.

Thanks for your suggestions and help.
