Map string keys to MySQL VARCHAR(128) instead of 255 to support 4-byte UTF-8
This is a backwards-incompatible change in that it may change your schema.
To obtain the old behavior you will have to explicitly re-map std::string
with the id_type pragma or explicitly specify the database type for each
affected id member with the type pragma.
