Yuck! At that point you're no better off than converting to hex (and
worse off than converting to base64) for storage.
SQL99 actually defines BLOB as a binary string literal comprised of an
even number of hexadecimal digits, in single quotes, preceded by "X",
e.g. X'1a43fe'. Should we be looking at implementing the standard
instead of, or in addition to, octalizing? Maybe it is possible to do
this by creating a new datatype, BLOB, which uses new IN/OUT functions,
but otherwise uses the various bytea functions?

I'll follow up on this then.
