If you’re using Heroku to host your Ruby Rack apps, then you’re probably also using Postgres, which is the default choice for the database stack.
However, one downside to this is that in development Postgres is a noisy bastard telling you about everything that you never wanted to know, plus the odd query of interest.
Well, luckily there is a couple of things you’re able to do to reduce the noise. Firstly you can tell Postgres directly that you don’t want to hear it’s warnings about table creation and the like:
development:
adapter: postgresql
host: localhost
min_messages: warning
database: foo_development
If this isn’t enough for you - you can also tell Postgres to only give you the queries that your app generates rather than everything that postgres sends over the wire. This is all handled by the silent-postgres gem.
To add, simply whack this in your gemfile.
gem "silent-postgres"
Bundle install, and you're good to go, and in peace.
