Resolution Note (fix version 2019.1):
We've corrected a problem was related to the AttributeType property of the CustomAttributeData type returned from TypeInfo.CustomAttributes. IL2CPP was providing the based class type (System.Attribute) instead of TableAttribute. The SQLLite code also uses the ConstructorArguments part of TypeInfo. Supporting this properly is difficult in IL2CPP now, as we will need to collect significantly more metadata and ship that metadata with the final build of a game. We're not planning to do that now, as it will increase distribution size too much.
