The server wouldn't. One of the implications of this requirement is
that we don't implement the feature on the server side, but in psql.
psql then checks isatty(fileno(stdin)) before allowing it.

Silently ignoring errors is almost always a really bad idea. Doing it
underneath an application that isn't expecting it is always a bad idea.
Perhaps more to the point, what we are talking about here is an option
to change the behavior of transactions from what it formerly was,
without any change in the SQL commands being issued. From a backwards-
compatibility standpoint this is monstrously dangerous. If you have
forgotten the server-side-autocommit fiasco, I suggest you go and read
the archives for a bit ...
