No, that's the way it's designed to work. It shows the objects that are
visible to you, without schema-qualifying them. See
http://www.postgresql.org/docs/9.0/interactive/app-psql.html#APP-PSQL-PATTERNS
:

> Whenever the pattern parameter is omitted completely, the \d commands display all objects that are visible in the current schema search path — this is equivalent to using * as the pattern. (An object is said to be visible if its containing schema is in the search path and no object of the same kind and name appears earlier in the search path. This is equivalent to the statement that the object can be referenced by name without explicit schema qualification.) To see all objects in the database regardless of visibility, use *.* as the pattern.
