* Most significant is probably the patching necessary to run plausible
with postgres without superuser privilege. This change includes:
* updating ecto_sql to 3.6 where `CREATE DATABASE` is only executed if
it doesn't exist[1].
* patching a migration to only modify the `users.email` column (to use
`citext` rather than creating the extension. `plausible-postgres`
takes care of that).
* Correctly declare dependencies in systemd.
* A few minor fixes.
