For blobs, it works with raw binary data.

Well, the man page says fully supports text BLOBs, I assume that binary not.
If HASH() behavior will operate ^Z and others control chars in Blob Image,
then now I need to think how to use this function to kill duplications.
Any function like CHECKSUM, CRC32,...?
