This was broken by:

We use sequelize with Redshift using the sequelize postgres dialect. It doesn't support the `standard_conforming_strings` option since it is based on an older version of postgres. Since https://github.com/sequelize/sequelize/commit/850c7fd04669e0fef9238b6dc4f8d6ee93ed71e9 was introduced, sequelize will try to set this option and fail, so I added a config option.
