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, keeping watch over their flock by night.
And, lo, the angel of the Lord came upon them, and the
glory of the Lord shone around them; and they were
sore afraid. And the angel said unto them, " Fear not;
for behold I bring you good tidings of great joy which
shall be to all people. For unto you is born this day
in the city of David a Saviour, which is Christ the
Lord." Luke 2:8-11
