That would serve equally well as an argument for returning the
compressed length of the string, I think. You'll need to do better.
My take on it is that when a particular client encoding is specified,
Postgres does its best to provide the illusion that your data actually
is stored in that encoding. If we don't make OCTET_LENGTH agree, then
we're breaking the illusion.
