I found the pg_hba.conf file in c:\Program Files\postgreSQL\8.1\data. It
appears to contain a vast amount of text following "#" symbols (which I
gather means that the text is there for my information only, ignored by the
computer). The only line of text that is not prefaced with "#" is this
(this is referenced as IPv4):

host all all 127.0.0.1/32 trust

A similar line of text below this one, referenced as IPv6, is this:

#host all all ::1/128 trust

So that's the pg_hba.conf file information. What I'm doing is this:

1. In Windows, through the Start menu, I select "Start service"
2. I wait for "Start service" to open and close a command shell (usually
too fast to see more than a flicker)
3. In Windows, through the Start menu, I select "Command prompt"
4. A command shell opens, giving me the prompt:

C:\Program Files\PostgreSQL\8.1\bin>

5. I type:

C:\Program Files\PostgreSQL\8.1\bin>createdb mydb [enter]

6. The system yields the following error:

createdb: could not connect to database postgres: FATAL: role "emc"
does not exist

7. I am left back at the prompt.
8. Not to be deterred, I type:

C:\Program Files\PostgreSQL\8.1\bin>createuser emc

9. The system gives me a prompt:

Shall the new role be a superuser? (y/n)

10. I type "y" [enter]
11. The system yields an error message:

createuser: could not connect to database postgres: FATAL: role "emc"
does not exist

12. I open Outlook and email the Novice List.

I think that it's noteworthy that pgAdmin III lets me perform the tasks of
making new databases without trouble. This tells me that the tasks can be
done on my computer, but that I'm leaving out some basic step. (To give you
an idea of how basic, I spent ten minutes getting the error that the port
wasn't listening. I finally stumbled to the trick that I had to "start
service" first. That gives you an idea of the sort of basic step I'm apt to
miss out of sheer ignorance.)
