referencial integrity constraint bug in version 7.0 beta 5

I am running a slackware 7 linux box (kernel 2.2.14 g++2.91.66) and i 've
installed the ver 7 beta 5. So i had the following problem

I suppose when you make a constraint statement for reference key theere
should be a check for the fields names , example:

create table tbl1 (p1 int2 primary key,p2 int4);
and:
create table tbl2(p1 int2 primary key, p2 int2, constraint lala foreign
key (p2) references tbl1(po1));
(the o in po1 was misstyped)
there was no error message( i didn't noticed it too)
when i 've tryed the :
insert into tbl1 values (1,1);
i got the the error that the there was no field 'po1' for the constraint
procedure to check.
maybe that's because it's a beta version ........
if this was reported earlier excuse me but i am new to the list
