I see this in 7.2 docs. This is not mentioned anywhere in current docs.
Does it work with other auth mechanisms (md5, crypt)?
The format of a text password file is one entry per line; the fields
of each entry are separated by colons. The first field is the user
name, the second field is the encrypted password. Other fields are
ignored (to allow password files to be shared between applications
that use similar formats). <application>pg_passwd</application>
enables users to interactively add entries to such a file, to alter
passwords of existing entries, and to encrypt such passwords.
To make use of this password file, put a line like the following in
host mydb 220.127.116.11 255.255.255.255 password passwords
which would allow access to database mydb from host 18.104.22.168 using
the passwords listed in the <filename>passwords</filename> file (and
only to the users listed in that file).
It is also useful to have entries in a password file with empty
password fields. (This is different from an empty password.) Such
entries allow you to restrict users who can access the system. These
entries cannot be managed by <application>pg_passwd</application>,
but you can edit password files manually.
