[ thinks about that... ]  Hmm, you're right, there is no mechanism to
cause the flat password file to be rebuilt after a restore.  So newly
created users won't be in it (and for that matter it won't reflect
post-backup password changes for existing users).  Just (re)assign any
one user's password and things should be ok.

Now that I think about it, this problem exists for ordinary crash
recovery from WAL as well.  We probably ought to just forcibly rebuild
the flat file at conclusion of any recovery.  Odd that it hadn't been
noticed already.
