I can't imagine adding many more, most likely zero. But, since there is some chance we will want another state, and since this is a DB field, we use the old "encode an enum as a single character" trick. The column itself is (or should be) a `CHAR(1)`. As a result, there an be no states with more than one letter. -- This is an automated message from the Apache Git Service.
