# NOTE: Why use Mysql2::Client / PG::Connection over ActiveRecord::Base.connection?
#
# As of Rails 5.2, db:create now runs initializers prior to creating the DB.
# That means if an initializer tries to establish an ActiveRecord::Base.connection,
# it will raise an ActiveRecord::NoDatabaseError
# (see https://github.com/rails/rails/issues/32870 for more details).
#
# The workaround is to use the bare RDBMS library
# and connect without specifying a database (MySQL),
# or connect to a standard system database instead (PostgreSQL).
