/* This is a dummy line to alter the dbscheme, so we can make a database upgrade

*
* 2021-07-14
*
* DO NOT remove this comment carelessly, since it can revert the dbscheme back to a
* previously seen state (matching a previously seen SHA), which would make the upgrade
* mechanism not work properly.
