why not copy bytea always in base64 encoded or similar format - this
will both save at least 2x the space on average random bytea data _and_
is probably faster, as it can be more easily done by table lookups in
bigger chunks

an alternative is to just escape minimal amount of characters, probably
just \0 , \n and \\
