Script to reproduce the problem.  It drops the tables at the end of the
script.  If data is not inserted into mtable there is no problem.
========================================================================================

create table utable (        uk int not null,pk int not null,thetext text,primary key (uk, pk) 
);    

create table mtable(id serial not null primary key,mtext text,o int,  /* corresponds to uk */p int  /* corresponds to
pk*/
 
);

insert into utable (uk,pk,thetext) values (2,4,'blah 2 4');
insert into utable (uk,pk,thetext) values (2,5,'blah 2 5');

insert into mtable (mtext,o,p) values ('m 2 4',2,4);


alter table mtable add FOREIGN KEY (p,o) REFERENCES utable (pk,uk);

drop sequence mtable_id_seq;
drop table mtable;
drop table utable;
