Question

I’m trying to run a previously working Rails 3 app with this configuration:

development:
  adapter: postgres-pr
  #encoding: utf-8
  host: localhost
  port: 5432
  database: name
  username: user-name
  password: user-password
  #pool: 5
  #timeout: 5000
  #reconnect: true

It’s the first time I use Postgres, so my configuration may be off. PGAdmin works, though.

pg_hba.conf has the following:

local   all             postgres                                peer

local   all             user-name                               password
host    all             user-name       127.0.0.1/32            password
host    all             user-name       ::1/128                 password

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5
# IPv6 local connections:
host    all             all             ::1/128                 md5

(I tried other configurations, it doesn’t seem to change things).

I get the error ActiveRecord::ConnectionNotEstablished whenever I try to load any page. The network trace reveals the following:

socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 9
setsockopt(9, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
bind(9, {sa_family=AF_INET, sin_port=htons(3000), sin_addr=inet_addr("0.0.0.0")}, 16) = 0
listen(9, 100)                          = 0
accept(9, {sa_family=AF_INET, sin_port=htons(50500), sin_addr=inet_addr("127.0.0.1")}, [16]) = 10
setsockopt(10, SOL_TCP, TCP_NODELAY, [1], 4) = 0
accept(9, 0xbf937aec, [16])             = -1 EAGAIN (Resource temporarily unavailable)
getpeername(10, {sa_family=AF_INET, sin_port=htons(50500), sin_addr=inet_addr("127.0.0.1")}, [16]) = 0

network,open trace doesn’t have the port 5432 either.

I can’t see the port that I wanted here, am I setting it in the wrong way? What else could be the problem here?

This is my ‘database.yml’, not using ‘port’ at all, maybe it can hint you in the right direction:

# PostgreSQL. Versions 7.4 and 8.x are supported.
#
# Install the pg driver:
#   gem install pg
# On Mac OS X with macports:
#   gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config
# On Windows:
#   gem install pg
#       Choose the win32 build.
#       Install PostgreSQL and put its /bin directory on your path.
#
# Configure Using Gemfile
# gem 'pg'
