I thought about that, but did not write it for a couple of reasons:

First, there wasn't a strong consensus that this type of function
belonged as part of libpq in the first place, so I didn't want to push
my luck ;-)

Second, at least in my current work, I'm using binary cursors, in which
case no unescaping is necessary.

I do agree that a standard bytea unescape function should be available
in the client library somewhere. Maybe for 7.3 . . .
