Test database for new installs?

Folks,

Some issues have come up repeatedly on IRC with new users, enough so that they 
might be worth addressing in the code:
a) new users try just to "psql" as postgres, and get a "no such database 
postgres";
b) new users use template1 as a testing database, and then have to re-initdb 
to clean it up.

Both of these things could be solved by creating an additional, non-template 
database called "postgres" at initdb.    For security reasons, this db would 
be set up in pg_hba.conf as accessable only by postgres via local.   It might 
not seem like it to experienced programmers, but having a "sandbox" database 
which lets you get used to PG commands would be a boon to people how are new 
to both Postgres and SQL databases in general.  

The only reason not to do it is space; each database takes up about 5mb.    
That's nothing to most users but could be a problem for a few.   Also, it 
would create a minor burden on the fsm to track an extra set of relations.
