myopinion it does a better job of local password management than using a ~/.pgpass file. Instead of assuming that a
modeof 600 will keep people from peeking at your password, it encrypts the password, but keeps the other parameters
likehost, port and user available for viewing as plaintext. You can read more about it here:

Looks rather like a postgresql service file. :)

This seems like it'd give people a false sense of security. If someone can read that file, they can log in to that
account.Obfuscating the password just makes naive users think they're secure when they're anything but, and means
they'reless likely to be careful about making that file unreadable and avoiding checking it into revision control and
soon. It'd protect against shoulder-surfing, but it's not like you're going to have .pg_pass open in an editor too
often.

A commandline tool for managing pgpass might be interesting, I guess. Though for local databases using peer
authenticationis likely better than saving passwords in a file.
