Similar to this question
I’ve updated both homebrew and postgresql. But I’m not sure how to connect this rails app with the updated version I installed. It clearly is still using 9.0.5 which was on the system, but I have 9.1.4 installed via homebrew, how do I change this to link it up?

Here’s the error I’m getting after running rake db:migrate:

pg_dump: server version: 9.1.4; pg_dump version: 9.0.5
pg_dump: aborting because of server version mismatch
rake aborted!
Error dumping database

I expect that you need to update your PATH environment variable so that rake finds the new pg_dump on the PATH before the old one, unless there’s a Rails-specific way to configure the pg_dump path explicitly.

Updating your PATH:
