Description by telackey:
  When doing a partial/FRI restoration the database files are copied
  key-by-key. This is necessary to reset the LSNs so the restored
  files can merge into the existing DB environment (cf. dblayer_copy_
  file_resetlsns()) in a recoverable way.

  However, dblayer_copy_file_keybykey() does not set the comparison
  function before calling DB->put(), which means that the restored
  files will not necessarily be using the proper function.

  While all the keys are technically present, indexed searches can
  still fail to return relevant results because the key order is
  significant when intersecting the results with the other indices.

  Note: The bug was reported and the patch was provided by telackey.
  (Thank you, Thomas!)

  Additional fix by nhosoi:
  The entryrdn index uses its special dup compare function.  The dup
  compare function is set when the restoring index file is entryrdn.
