Yep. I was wondering how we should do that for some time, but I was
not able to come back to it.

Hmm, OK. Consistency with DecodeInsert() is a good idea here, so
count me in regarding the way your patch handles the problem. I would
be fine to apply that part but, Andres, perhaps you would prefer
taking care of it yourself?
