  * PROBLEM DESCRIPTION:                                         *
  * When multiple tables are attached to a table which has an    *
  * index in the same dbspace as the table, it's possible to     *
  * construct data distributions for the leading column and      *
  * store it with incorrect column numbers in catalogs. Dbschema *
  * -hd will report an error for such a distribution.            *
  ****************************************************************
  * RECOMMENDATION:                                              *
  * Upgrade to 11.50.xC7 or higher.                              *

Problem conclusion

• Problem first fixed in 11.50.xC7.  A subsequent update
  statistics high or medium on the leading column will fix the
  issue.
