fkey + primary key does not work in current

It seems that foreign key does not work in current, if specified with
primary key definition. Take a look at following example(works in
7.0.2.):

test=# CREATE TABLE PKTABLE ( ptest1 int, ptest2 int, ptest3 int, ptest4 text, PRIMARY KEY(ptest1, ptest2, ptest3) );
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'pktable_pkey' for table 'pktable'
CREATE
test=# CREATE TABLE FKTABLE ( ftest1 int, ftest2 int, ftest3 int, ftest4 int, primary key
(ftest1,ftest2,ftest3,ftest4), CONSTRAINT constrname3 FOREIGN KEY(ftest1, ftest2, ftest3) REFERENCES PKTABLE);
 
NOTICE:  CREATE TABLE/PRIMARY KEY will create implicit index 'fktable_pkey' for table 'fktable'
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
ERROR:  columns referenced in foreign key constraint not found.

However, if primary key definition is not used with fkey, it works.

test=# CREATE TABLE FKTABLE ( ftest1 int, ftest2 int, ftest3 int, ftest4 int, CONSTRAINT constrname3 FOREIGN
KEY(ftest1,ftest2, ftest3) REFERENCES PKTABLE);
 
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
CREATE

Any thoughts?

Hmm, that's very strange.  I wonder which columns it think didn't exist.
It shouldn't be checking the pktable in that case, which would imply
it doesn't believe the existance of ftest1,ftest2,ftest3.  Probably
a stupid mistake on my part.  As soon as I clear off space to compile
current, I'll look.

Your message got though. I don't know the answer to your question, but
I'll bet that it is NO.

I believe that I sent a patch on Sep 17 for this to -patches although
I don't know if anyone saw it (it's in the archives, so I know it
went through).

That's strange.  I didn't see it.  Can you send it over.  The archives
don't seem to be working again.
