In future the similar structure is to be used for
an assignment of an index to a key cache: the index name will be added.
The name of the database catalog will be added as well.
The descriptors for the current assignments are put in the
assignment cache: assign_cache. If a table is not found in the cache
it is considered assigned to the default key cache.
