Hi Jim,
so IIUC, I will have to schedule a program on the server which reads all
user information and if a new user is added it modifies the pg_hba.conf and
reloads the server?
thanks,

I think you're basically stuck with pg_hba.conf. There's been some functions
added to 8.1 that make it possible to do some more administrative stuff with
config files via SQL, but I'm not sure if they'd cover this case.
I can see where this could be a problem for people providing hosting; if
enough other users request this functionality it might make it onto the TODO
list.
