Socket File “/var/pgsql_socket/.s.PGSQL.5432” Missing In Mountain Lion (OS X Server)

Question

I just upgraded my MacMini Server from Lion Server to Mountain Lion using OS X Server. I am having the same problem with PostgreSQL that I did last year when I first instal

Answer 1

As mentioned by others in the comments, a really simple solution to this issue is to declare the database 'host' within the database configuration. Adding this answer just to make it a little more clear for anyone reading this.

In a Ruby on Rails app for example, edit /config/database.yml:

development:
  adapter: postgresql
  encoding: unicode
  database: database_name
  pool: 5
  host: localhost

Note: the last line added to specify the host. Prior to updating to Yosemite I never needed to specify the host in this way.

Hope this helps someone.

Cheers
