“pg_dump: invalid option — i” when migrating

Question

When I run rake db:migrate on my Rails project (3.2.22.2) I get pg_dump: invalid option -- i. Here\'s the full trace:

Celluloid 0.1         


        

Answer 1

I've recently got this very error with Rails 4.2.1 after trying to run rake db:migrate.

I was able to overcome it by upgrading to Rails 4.2.6 and letting bundle update do it's job bumping all related gems.

Hope that becomes useful to others.
