It's the default database for tools like createdb, createuser,
createlang, dropdb, dropuser, etc.

This is a pgAdmin message. It doesn't mean you can't drop it with the
usual way (DROP DATABASE statement, or the dropdb tool), or with pgAdmin
(but you first need to change the maintenance database of your server...
BTW, the maintenance database is an expression specific to pgAdmin).

Well, you can drop it or rename it. It will make your life quite hard
with the usual tools (createdb and the like). It's way better to add a
new database, and keep the postgres database.
