@item @code{ENUM_FLAG}           @tab Field is an @code{ENUM} (deprecated)

@item @code{SET_FLAG}            @tab Field is a @code{SET} (deprecated)

flags is deprecated because they indicate the type of a field rather

@code{field->type} against @code{FIELD_TYPE_BLOB},

@code{FIELD_TYPE_ENUM}, or @code{FIELD_TYPE_TIMESTAMP} instead.
