column names in select don't exists in insert to

Hi,
I encountered a strange problem while trying to solve a bug. I use a
postgresql 8.x database and a jdbc driver from
postgresql-8.1dev-400.jdbc3.jar. The following is happening

The table is created like
create table test (
field1 int8 not null,
field2 int8 not null);

if I do a

select field1 from test;

results are returned normal, no problems at all, but when i do a

insert into test (field2, field1) values (1, 2);

It complains that field1 doesn't exists.

Has anyone encountered this same problem or does have anyone a pointer
for a bit more info on this problem?

Thanks,

Johan
