I've marked it as "Rejected" now, as that is clearly the consensus. > But I think we should edit the documentation a bit. > > I don't fully understand those who want to handle it by a script, > but the documentation seems to be suggesting that something like > is possible.

The documentation says "For the purpose of testing replication commands", one could use psql and "IDENTIFY_SYSTEM", it doesn't exactly suggest to run BASE_BACKUP this way. Which, by the way, appears to be working totally fine from psql, modulo the problem that you won't get to the starting transaction location. > "psql doesn't handle this protocol properly.
