Dopo aver effettuato l'aggiornamento e la preparazione, i miei postgres hanno avuto qualche problema. Ho provato a disinstallare Postgres e installarlo di nuovo, ma non ha funzionato altrettanto bene.
Questo è il messaggio di errore. (Ho anche ricevuto questo messaggio di errore quando provo a eseguire rake db: migrate)
$ psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Come posso risolverlo?
Versione per Mac: leone di montagna.
versione homebrew: 0.9.3
versione postgres: psql (PostgreSQL) 9.2.1
E questo è quello che ho fatto.

The files belonging to this database system will be owned by user "laigary".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.UTF-8".
The default text search configuration will be set to "english".
initdb: directory "/usr/local/var/postgres" exists but is not empty
If you want to create a new database system, either remove or empty
the directory "/usr/local/var/postgres" or run initdb
with an argument other than "/usr/local/var/postgres".

Ora, dopo aver reinstallato howbrew, quando lo uso $ psql
, non mostra alcun messaggio di errore.
Ma corro rake db:migrate
nella mia app Rails, mostra:
could not connect to server: No such file or directory

Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "database"=>"riy_development", "pool"=>5, "username"=>nil, "password"=>nil}
Finalmente trovo la soluzione.
$ sudo mkdir /var/pgsql_socket/
$ sudo ln -s /private/tmp/.s.PGSQL.5432 /var/pgsql_socket/
Questa soluzione è un po 'complicata, ma funziona. Spero che qualcuno abbia una soluzione migliore
Aggiornare
Questo funziona anche per me.
