>Description:
Testing has revealed that when the category field is missing from dbconfig of a 
database, gnatsd segfaults upon CHDB to the database. (It seems that all other 
builtin fields can be removed without catastrophic problems.)

I do not think it is easily possible to remove this dependency since GNATS uses 
directories named after categories to organize the database, so we need to 
catch a missing category field definition and tell the user that the GNATS 
installation is broken.
