Another naive question, inheritance and foreign key

Hi,

Just stumbled upon this. Is it correct to conclude that foreign keys are not
inherited from this text?

--------------------
phd=# create table perbookings(type smallint) inherits (bookings);
CREATE TABLE
phd=# \d perbookings;
Table "public.perbookings"
Column | Type | Modifiers
--------+-----------------------------+----------------------------------
rid | integer |
uid | integer |
stime | timestamp without time zone |
etime | timestamp without time zone |
bid | integer | default nextval('bid_seq'::text)
type | smallint |
Check constraints: "bookings_etime" (etime > stime)

phd=# \d bookings;
Table "public.bookings"
Column | Type | Modifiers
--------+-----------------------------+----------------------------------
rid | integer |
uid | integer |
stime | timestamp without time zone |
etime | timestamp without time zone |
bid | integer | default nextval('bid_seq'::text)
Check constraints: "bookings_etime" (etime > stime)
Foreign Key constraints: $1 FOREIGN KEY (rid) REFERENCES resource(id) ON
UPDATE CASCADE ON DELETE CASCADE,
$2 FOREIGN KEY (uid) REFERENCES users(userid) ON
UPDATE CASCADE ON DELETE CASCADE

phd=# select version();
version
---------------------------------------------------------------------
PostgreSQL 7.3.2 on i386-portbld-freebsd4.7, compiled by GCC 2.95.4
(1 row)
--------------------

TIA..
