Oh, I see. But I still don't think we really need to provide specific
examples of what you get when you MD5 particular values... except for
people who can run the MD5 algorithm in reverse in their head, that
doesn't seem like it's adding anything. Second try:
Either the user's unencrypted password (if the UNENCRYPTED option was
used when creating the role or if password_encryption is off), or the
string 'md5' followed by a 32-character hexadecimal md5 hash. The md5
hash will be of the user's password concatenated to their username
(e.g. if user joe has password xyzzy, PostgreSQL will store the md5
hash of xyzzyjoe). If the user has no password, this column will be
NULL.
