Logged by: Nicolas Addington

PostgreSQL version: 8.0
Operating system: aix
Description: invalid input syntax for integer: ""
Details:
When a pl/perl trigger for an insert event changes an integer column in the
new row to null, it fails. Interestingly, it doesn't have a problem if the
column was originally null.
create table tbl ( id integer primary key, n integer );
create function trg() returns trigger as $$
undef $_TD->{new}{n};
return 'MODIFY';
$$ language 'plperlu';
create trigger trg before insert on tbl for each row execute procedure
trg();
insert into tbl values (1, null);
INSERT 17997 1
insert into tbl values (2, 0);
ERROR: invalid input syntax for integer: ""

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
