I'm no expert, but I've dozens of PostgreSQL databases running mostly
without manual maintenance for years, just do the backups, and you are fine.
In any way, if you need any kind of maintenance, you can program it in
your app (even backup, restore and vacuum) - it is easy to throw
administrative commands thru the available interfaces.
And if the database get out of access, no matter if it is centralized or
remote: you will need someone phisically there to fix it.
AFAIK, you don't even PostgreSQL installer - you can run it embed if you
wish.
