Yes, I've just been looking at that. I think this is probably a hangover 
from when these routines were recast to some extent. Given that we're 
not seeing any errors from it, I'd be inclined to remove the the "|| 
val->type == jbvBinary" part. One of the three call sites to 
convertJsonbValue asserts that this can't be true, and doing so doesn't 
result in a regression failure.

Peter and Teodor, comments?

cheers
