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
********* QUERY **********
SELECT relhasindex, relkind, relchecks, reltriggers, relhasrules

**************************

********* QUERY **********

Hope to hear from you.
