  85 What about the following:\r
  86 \r
  87 - increase NOTMUCH_DATABASE_VERSION[1]\r
  88 - update notmuch_database_upgrade[2] to fill in the new data for the\r
  89 documents missing it\r
  90 - include an upgradedb command that wraps notmuch_database_upgrade[2]\r
  91 - have notmuch search prints a warning about running a DB version less\r
  92 than the runtime and suggests running upgradedb\r
