Closes #3469
When initializing abstract (
ActiveRecord
) models,#table_exists?
is used and calls through theconnection
, which (in the case of aprecompile
step) can raise errors other than theActiveRecord::NoDatabaseError
that's currently handled.I believe this should cover all PostgreSQL and MySQL connection errors handled by Rails.
