Really?  If pgAdmin has a password-change function that doesn't use
client-side password encryption then somebody should file a bug against
it.  Sending unencrypted passwords exposes the password at least to the
postmaster logfile.  createuser has been doing encryption, unless
specifically commanded not to, for a long time.
