Съжалявам, че тичам из SO публикации повече от ден и просто се чувствам така, сякаш не отивам никъде. Наскоро актуализирах софтуера си до Mavericks и приложението ми rails вече не работи. По-конкретно моята psql база данни не работи. Когато напиша psql в моята конзола, той връща „не можа да се свърже със сървъра: Връзката е отказана...“ и когато насоча сървъра, получавам „PG Connection Bad“ със същия текст.
Ето моя файл pg_hba.conf:
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication Brian_Liou trust
#host replication Brian_Liou 127.0.0.1/32 trust
#host replication Brian_Liou ::1/128 trust
Ето моя postgresql.conf

Опитах се да премахна тази папка: /usr/local/var/postgres и след това да преинсталирам postgresql с помощта на brew.
Моят Bash профил включва
export PGDATA=/usr/local/var/postgres
export PGHOST=localhost
Знам, че проблемът е свързан с Postgres, който Mac инсталира автоматично и този, който brew инсталира, освен че съм напълно изгубен. FYI Аз също съм начинаещ в rails/програмист. Моля, уведомете ме за допълнителна информация, която мога да предоставя, за да разреша този проблем!
