-1. There's nothing wrong with the function-as-a-computed-column
feature, and it seems likely that taking it away will break applications.
What we are getting bit by is that I/O coercions to string types can be
specified this way. Maybe what we ought to do is remove just that one
capability. It'd be a bit non-orthogonal, but seems fairly unlikely to
break anything, especially since we only began to allow such things
recently (in 8.4 looks like).
