Not sure what your point is here. If an interface is going to support
more than one value of a parameter, then yes it has to be sure to do the
right thing in each affected place. There's no shortcut for that.

My thought is to put it in the clients. All except libpq already have
some such logic, and it worked well enough except for their inability to
be completely sure of the backend's state --- which we will fix with the
protocol revision. The server-side implementation has turned out to be
a complete mess.
