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@wombat bin]$ ./psql postgres ilejn

postgres=# drop table ddd;

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.
