+#starting to take quite a while for big dbs

+# - seq scan of cust_main on paydate... index on substrings?  maybe set an
+#    upgrade journal flag now that we have that, yyyy-m-dd paydates are ancient
+# - seq scan of cust_main on payinfo.. certainly not going toi ndex that...
+#    upgrade journal again?  this is also an ancient problem
+# - otaker upgrade?  journal and call it good?  (double check to make sure
