Maintenance is required for your database

Your database HEROKU_POSTGRESQL_IVORY_URL on myrisha1 requires maintenance. During this period, your database credentials will become read-only. Once it has completed, your database URL will have changed, but we will update your app's config variables accordingly. This automated maintenance is a necessary part of our Hobby tier plans, Dev and Basic. Should you need more control over maintenance windows, a production database (Standard tier or higher) offers more control over database maintenance, as we are able to schedule them in advance and provide better tools for self-served maintenance. We expect maintenance to last just a few moments depending on the size of the database. We will notify you when maintenance begins, and again once it's complete.
