Yes, that's why my code had a special case for 'postgres' or whatever
super-user name it was installed with. I think it is cleaner to just
read the install username. Also, right now, pg_pwd only contains
usernames that have passwords, not all of them.

I thought they were talking about increasing the length of the user NAME
that comes of the wire. That is currently 32. I see now he was just
talking about NAMEDATALEN. Good thing we are prepending the database
name after receiving the name.
