FYI, 9.3 is now up to 9.3.17:

https://www.postgresql.org/docs/9.3/static/release.html

At some point, once you have gotten a handle on using Postgres, you
should probably update. Read the Release Notes for each of the minor
releases to see what has been fixed.

So when you did this:

"
psql -U otherusername -d database

… I get:

psql: FATAL: Peer authentication failed for user "otherusername"

"

you where connecting using local, which is the socket connection.

If you had done:

psql -U otherusername -d database -h localhost

it would have asked for a password(md5 auth method). If otherusername
does not have the LOGIN attribute you would not been able to log in
anyway. For more detailed information see:
