Relation "pg_relcheck"

Hello.

I'm running PostgreSQL 7.3.2 on i686-pc-linux-gnu, compiled by GCC 2.95.3.

I've created a table (a forest of nested sets):
create table forest (
tree_id int4 not null,
leaf_id int4 not null,
lid int2 not null check(lid > 0),
rid int2 not null check (rid > 1),
relation_id int2 not null default 0,
constraint forest_order check(lid < rid),
constraint forest_primary primary key(tree_id, leaf_id)
);

Now, in psql:
mema2=> \d forest
ERROR: Relation "pg_relcheck" does not exist

Whats the problem, I wonder. I've already created a new DB location with
initdb and pointed server to it - same stuff.

psql -E gives the following:

mema2=> \d forest
