That’s basically what I tried before, though I just string-reversed the
MD5 hash so that I could un-reverse it. I also prefixed “md5” with '-'
so I could tell which passwords were scrambled.

What I found was that a “suspended” user could still log in, though.

I looked for some control to “reload” the passwords from that datastore
but couldn’t find any.

I also did this on pg_authid; would that have made a difference?
