- All the functions querying table options could return information from the wrong
  table when several CONNECT tables were used in the same query (for instance joined
  together) This was because they belonged to the catalog class that is shared between
  all tables in the same query. They have been moved from the catalog class to the
  TABDEF/RELDEF class that is attached to each table. This was a major potential bug.

  in this version. Sure enough, it never caused any improvement in
  the execution speed and rather caused a small increase of execution
  time. This is probably because values are sorted by rowid in each
  range of CONNECT indexes. This could be reconsidered if a customer
  have a need for processing very big files.
