RI problem with inherited table

It no longer seems to be possible to refer to a table, which is an
ancestor of any other, in a referential integrity constraint.

In this example, "person" is the ancestor of several other tables:


bray=# create table junk (id char(10) constraint junk_id_person references 
person*(id));
ERROR:  parser: parse error at or near "*"
bray=#  create table junk (id char(10) constraint junk_id_person references 
only person(id));
ERROR:  parser: parse error at or near "only"
bray=# create table junk (id char(10) constraint junk_id_person references 
person(id));
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
CREATE
bray=# insert into junk values ('aa');
ERROR:  SELECT FOR UPDATE is not supported for inherit queries

========================================   "And there were in the same country shepherds abiding      in the field,
keepingwatch over their flock by night.     And, lo, the angel of the Lord came upon them, and the     glory of the
Lordshone around them; and they were      sore afraid. And the angel said unto them, " Fear not;     for behold I bring
yougood tidings of great joy which     shall be to all people. For unto you is born this day      in the city of David
aSaviour, which is Christ the      Lord."        Luke 2:8-11
