A key difference between the "postgres" DB and a default table is that
the "postgres" DB is very convenient with PostgreSQL's default of
connecting to a DB of the same name as the user.

We don't have a corresponding


    SELECT fred;

where there is some invisible implicit table name.

Personally I wish Pg was able to start w/o "connecting" to any specific
DB, but that's just not how the architecture works, and with that
limitation the "postgres" DB seemed like a good compromise. (That said,
it's really weird that the username of the superuser defaults to the
current unix user when initdb'ing, but the db created by default is
still always "postgres").
