The following sequence, which works in 7.0.2, now fails in current
sources:
CREATE TABLE person
(
ptype SMALLINT,
id CHAR(10) PRIMARY KEY,
name TEXT NOT NULL,
address INTEGER REFERENCES address (id)
ON UPDATE CASCADE
ON DELETE NO ACTION,
salutation TEXT DEFAULT 'Dear Sir',
envelope TEXT,
email TEXT,
www TEXT,
CONSTRAINT person_ptype CHECK (ptype >= 0 AND ptype <= 8),
FOREIGN KEY (id, address) REFERENCES address(person, id)
ON UPDATE CASCADE
ON DELETE RESTRICT
)
NOTICE: CREATE TABLE/PRIMARY KEY will create implicit index 'person_pkey' for

ERROR: columns referenced in foreign key constraint not found.
I think this means that the FOREIGN KEY installer thinks that table
"individual" does not have columns "id" and "address", which are
inherited from "person". However, if this is correct, the wording of the
error message is poorly chosen, since it seems to refer to the columns
mentioned after the REFERENCES keyword.
