OK, I sent out a note to pgsql-general and pgsql-sql about that.

You mean, not only the current backend but other people's backends?
I can't see any very simple way to do that, and without a pretty
compelling use-case I'm not going to worry about it.

So far nobody's commented on the question of exactly what should be
saved and restored for a cached query's search_path.  I think for the
moment I will go with the save-a-list-of-schema-OIDs approach, since
that seems fairly unlikely to be subvertible by a miscreant user.
We can always change the details later.
