table is not a table

Hello!

Could you please help me with an issue I have on a PG installation.
The problem is it is impossible to drop any table.

Looks like this.

[ilejn(at)wombat bin]$ ./psql postgres ilejn

postgres=# create table ddd(f1 int4);
CREATE TABLE
postgres=# drop table ddd;
ERROR: "ddd" is not a table
postgres=# select * from pg_authid where rolname='ilejn';
rolname | rolsuper | rolinherit | rolcreaterole | rolcreatedb | rolcatupdate | rolcanlogin | rolconnlimit | rolpassword | rolvaliduntil | rolconfig

(1 row)
postgres=# select * from pg_tables where tablename='ddd';
schemaname | tablename | tableowner | tablespace | hasindexes | hasrules | hastriggers
------------+-----------+------------+------------+------------+----------+-------------
public | ddd | ilejn | | f | f | f
(1 row)
postgres=# alter table ddd add column f2 text;
ALTER TABLE

There is no magic about 'ddd' - same thing for every table.
I can ALTER this 'ddd', I can do any DML, but cannot drop!

Any ideas what's wrong with permissions/roles or something?

Thanks.
