I'm sorry to hear about this problem.
Not sure we need a LOG message to warn people about the possible lengthof recovery time. The chances of a recovery taking that much time seemvery low for normal Postgres, even with checkpoint parameters set attheir maximum values.
I note that the configuration section does not mention the likelyincrease in recovery time that will result from setting those parametershigher. That needs a patch. ISTM a serious omission that should betreated as a bug and backpatched.
