I'm not joking, and don't call me Shirley. If you are running into situations
where you have question mark operators in your queries, you have already lost
the query abstraction battle. There will be no seamless switching if you
are using jsonb, hstore, ltree, etc. My statement was more about pointing out
that Postgres already offers a complete placeholder system, which drivers
are free to implement if they want.

Well, they will have to adapt to one way or another: using ?? or \? is doing
so, and the other solution (Postgres adapting itself to the driver by
deprecating the ? operator) is not realistically likely to happen.
