I'm working on some infrastructure around this. Not sure if it needs to
be committed, but it's certainly useful for evaluation. Basically it's
a small UDF that:
1) creates a slot via walsender protocol (to some dsn)
2) imports that snapshot into yet another connection to that dsn
3) runs some query over that new connection
That makes it reasonably easy to run e.g. pgbench and continually create
slots, and use the snapshot to run queries "verifying" that things look
good. It's a bit shoestring-ed together, but everything else seems to
require more code. And it's just test.
Unless somebody has a better idea?
