On what basis do you expect that? Every time you use a view, you're
using a pg_node_tree. Nobody's ever complained that having to reload
the pg_node_tree column was too slow, and I see no reason to suppose
that things would be any different here.
I mean, we can certainly invent something new if there is a reason to
do so. But you (and a few other people) seem to be trying pretty hard
to avoid using the massive amount of infrastructure that we already
have to do almost this exact thing, which puzzles the heck out of me.
