As per the documentation, for ActiveRecord integration, all that is required is to run rails db:migrate This also adds the errors table in to the schema.rb file.

The problem is then whenever anyone calls rails db:reset it gets the database configuration from the schema.rb and creates the errors table.

When db:migrate is used again (such as to complete a later migration), it tries to create the errors table again throwing a duplicate table error.

Steps to reproduce

1. run rails db:migrate to create the errors table and update schema.rb
2. run rails db:reset to reset the database as per the schema file
3. run rails db:migrate again to get the exception handler gem to try and recreate the table again

Expected behaviour

Exception handler should know that a table with the same name (and/or same columns) already exists and not try to recreate the table

Actual behaviour

Exception handler tries to recreate the errors table
