that 'edge case' is one in which postgres isn't running. you have to
run initdb to initialize the database cluster before you can start the
postmaster. initdb creates template0, template1, and, in 8.x and newer,
postgres databases

the postgres database administrator account can do...

$ psql -l

to list all databases, or...

$ psql
....
postgres=# \l

or, in sql, while connected to {template1 | template0 | postgres | ... }

select datname,... from pg_catalog.pg_database;
