But would it work for non-transactional storages like file systems?

Nope, unless it's a journaled filesystem and we pulled out the journal log entry number. ;-)

So would it be good to have all three kinds of hooks then?

Yes. I've looked, but I can't find a way to ask Postgres for the transaction ID, though I did find LISTEN/NOTIFY which ought to provide good invalidation notification. Shane
