“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

Unlikely there is a fix as it's not a security issue. Even if it was, I'm not sure they are patching 3.x anymore.

The problem is in the db:structure:dump task here:

https://github.com/rails/rails/blob/v3.2.22.2/activerecord/lib/active_record/railties/databases.rake#L428

Easiest thing is to copy that task (413 - 448) and put it into your own lib/tasks directory, wrap a namespace db around it, tweak the pg_dump command (remove -i) and your task should override the built in task.
