What John said, but just a small note. The text representation of the
various datatypes are fairly static. The binary representations can
change - even between two databases with the same version number
(floating-point vs big-int timestamps). For a meaningless (to the db)
"blob" type that doesn't matter, but you will need to be aware of the
issues and have appropriate tests in place for your application.
