Syntax:  DELETE PACKAGE package_name_wild

  Deletes the package(s) specified.

  The routines and parameters associated with the package are not
  deleted, but they are no longer available for use.  If a subsequent
  NEW PACKAGE command is entered for the same package name, then all
  the previously defined routines and parameters become associated with
  the new package definition.  Thus, you can use the DELETE PACKAGE
  command, followed by the NEW PACKAGE command, to modify the
  properties of a package definition.
