Cannot Connect To PostgreSQL Database

Question

I am trying to connect to my database through R, but am getting an error. My coworker connects perfectly with the same exact script. Anyone know what else could be the problem? We have the same packages installed.

Answer 1

PostgreSQL servers control who they listen and talk too. You did well comparing the same script between machines, but you may be coming from different subnets, or any other difference which would tickle this behaviour.

On my box, this is controlled by the file /etc/postgresql/9.1/main/pg_hba.conf -- hba stands for host-based access.

So you may have to talk to your DBA or sysadmin.
