Decided to try postgresql. Downloaded latest version,(v8.0.0), had to
hack a bit to install it (it looks for msiexec.exe in the temp
directory, not in my path, I don't know ANYBODY who keeps windows
system files in his temp directory, but .....).
Started on docs, and tada .... my first command:

..............

To create a new database, in this example named mydb, you use the
following command:

$ createdb mydb

This should produce as response:

CREATE DATABASE
................
createdb
unknown command. Not to be found anywhere on my PC.
Is this some kind of a newbie joke ?
