Following up my own mail, I found at least one solution in the
meantime; there was a proper backup of master.passwd in /var/backups;
and on that file pwd_mkdb worked.  The question remains, however,
what to do in the case when only the databases are left and all
textual files are trashed.  Surely there must be a way to create
the text files from the db?
