> Here's the code roman:

I had no problem with your code if my table is defined:

create table tblcat (id integer);
insert into tblcat values(1);
insert into tblcat values(2);
insert into tblcat values(3);
insert into tblcat values(4);

I get in stdout:

1
2
3
4

So, could you please post database metadata that are related to this
table. I tried to create table "tblcat;" or "tblcat" but then I had
message "Table ... unknown". That's error code -204, not -901.

So, please post your metadata and the server (build version) you use
(maybe this is somewhere in previos messages, but I would be very
grateful if I do not need to seach them ;)).

Best regards,
