Remove this, just get info from file name?

Thanks for your advise! I was thinking that this is convenient for sql. For example, if we want to calculate all blob's storage, we just need to write where T.blob = true instead of where T.fileName LIKE '%s.blob'.
Would you be okay with keeping this boolean field, or do you prefer avoid persisting redundant metadata?

This system table should just reflect the schema of data file meta, so I think it is better to remove this.
