Principles of Adult Behavior

Be patient. No matter what.
Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
Never assume the motives of others are, to them, less noble than yours are to you.
Expand your sense of the possible.
Don’t trouble yourself with matters you truly cannot change.
Expect no more of anyone than you can deliver yourself.
Tolerate ambiguity.
Laugh at yourself frequently.

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book.

Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

psql: FATAL: Peer authentication failed for user “postgres” (or any user)

The connection failed because by default psql connects over UNIX sockets using peer authentication, that requires the current UNIX user to have the same user name as psql. So you will have to create the UNIX user postgres and then login as postgres or use sudo -u postgres psql database-name for accessing the database (and psql should not ask for a password).

If you cannot or do not want to create the UNIX user, like if you just want to connect to your database for ad hoc queries, forcing a socket connection using psql --host=localhost --dbname=database-name --username=postgres (as pointed out by @meyerson answer) will solve your immediate problem.

But if you intend to force password authentication over Unix sockets instead of the peer method, try changing the following pg_hba.conf* line:
