This makes the parameter easier to extend, to support other password-based authentication protocols than MD5. (SCRAM is being worked on.) The GUC still accepts on/off as aliases for "md5" and "plain", although we may want to remove those once we actually add support for another password hash type. Michael Paquier, reviewed by David Steele, with some further edits by me. Discussion: <CAB7nPqSMXU35g=W9X74HVeQp0uvgJxvYOuA4A-A3M+0wfEBv-w@mail.gmail.com>
