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:

ATM Machine Kata

El siguiente es un ejercicio para codificar, refactorizar y hacer pruebas, en el cual puedes invertir de 15 a 30 minutos para resolverlo gradualmente.

Antes de que empieces

• Intenta no adelantar la lectura.
• Realiza una tarea a la vez. El truco para aprender es el trabajo incremental.
• Asegurate de hacer las pruebas para las entradas correctas. No hay necesidad de probar entradas inválidas.
• De vez en cuando haz un refactor de tu código.

Haskell

Functions

Is a mapping that takes one or more arguments and produces a single result.

• Is defined using an equation with a name for the function

• Each argument has a name

• The body specifies how would be calculated in terms of the arguments
