commit 77ac8a925ba59552b1bab9b85e2fa63275eebca3
Author: Galen Charlton <gmc at esilibrary.com>

    After upgrade, list records with missing or incorrect 901$c
    
    This is a common cause of pain for upgrades. Let's try to identify the
    problem early (even if it takes forever on a site with 3 million bibs)
    and offer advice on correcting the problem if it is flagged.

+\qecho Evergreen depends heavily on each bibliographic record containing
+\qecho a 901 field with a subfield "c" to hold the record ID. The following
+\qecho query identifies the bibs that are missing 901s or whose first
+\qecho 901$c is not equal to the bib ID. This *will* take a long time in a
+\qecho big database; as the schema updates are over now, you can cancel this
+\qecho if you are in a rush.

+\qecho If there are records with missing or incorrect 901$c values, you can
+\qecho generally rely on the triggers in the biblio.record_entry table to
