including gem but setting HerokuRequestId::Middleware.log_line to false in development causes errors

[bodaro]

If I use this gem during local development (not on heroku) I see this as part of the logs for each request:

2013-09-16 00:05:20 [FATAL]
ActiveRecord::ConnectionTimeoutError (could not obtain a database connection within 5 seconds. The max pool size is currently 5; consider increasing it.):

I cannot conditionally include the gem because I sometimes run a staging or production RAILS_ENV from my local environment (aka laptop).

I am hoping that setting log_line to false would mean the gem does nothing and stops making these strange errors.

Also, I would really like to see not only a log line showing the heroku request ID but also the current request session ID (from the session cookie) so I can track a given user across requests (would be super awesome in papertrail).

Further, I would also love to have the heroku request ID and the session ID appeneded to each and every heroku log line. Is this possible?

Here is my logs showing the error (with more context):
