Avoid Foreign Key Constraints in Database Schemas to support Vitess

Hi,

I investigated the use of Ghost with Planetscale.com, which is based on Vitess. Unfortunately Vitess does not support Foreign Key Constraints, which makes it impossible to use it as a database for Ghost.

While I totally understand that this might not be a priority, I wonder wether it is worth discussing removing key constraints (and working with alternatives) in order to extend support for MySQL-based databases like Vitess?

Kind regards,

Christoph
