I have 4 environments between my local, dev, staging, and production.
A large amount of content is published to the staging environment on a daily basis, so that is the center of my workflow. Once content is QA'ed in staging it is then sql-sync'ed to production. This works fine at the moment. However, we're now going to allow for user registration/user generated content. Is there a way to push these content updates with sql-sync and never overwrite certain tables? Even more specifically, is there something I can place in drushrc.php that will always skip a list of tables across all environments?
