Subject: [HACKERS] password authentication This patch adds support for plaintext password authentication. To use it, you add a line like host all 0.0.0.0 0.0.0.0 password pg_pwd.conf to your pg_hba.conf, where 'pg_pwd.conf' is the name of a file containing the usernames and password hashes in the format of the first two fields of a Unix /etc/passwd file. (Of course, you can use a specific database name or IP instead.) Then, to connect with a password through libpq, you use the PQconnectdb() function, specifying the "password=" tag in the connect string and also adding the tag "authtype=password". I also added a command-line switch '-u' to psql that tells it to prompt for a username and password and use password authentication.
