How does one launch PhpPgAdmin?

I just installed postgresql, php5 and in particular PhpPgAdmin using Ubuntu's synaptic app. The PHP is running fine, the http server (lighttpd) is working fine, and I can do pg a the command line. The only thing that remains a mystery is PhpPgAdmin - just how does one fire it up to use it? I am clueless about the proper means of starting PhpPgAdmin; it isn't explained anywhere on the site for it. I tried typing phppgadmin at a bash command prompt, and entering "http://phppgsdmin/" and "http://localhost/phppgadmin" as wild guesses in the address bar in a browser - nothing happens. What is the secret?

BTW, i'm only serving http on localhost, doing purely private web development.

Have you set up phppgadmin in the lighty config?

alias.url = ("/pgadmin" => "/usr/share/phpPgAdmin")

You also have to enable mod_alias in Lighty (and restart it) and then "http://localhost/pgadmin" should work ...
