Hi, Based on a couple of independent reports from users with no idea how to judge the progress of a system recovering from a crash, Christoph and I wondered if we should override update_process_title for the "recovering ..." message, at least until connections are allowed. We already do that to set the initial titles.
Crash recovery is a rare case where important information is reported through the process title that isn't readily available anywhere else, since you can't log in. If you want to gauge progress on a system that happened to crash with update_process_title set to off, your best hope is probably to trace the process or spy on the files it has open, to see which WAL segment it's accessing, but that's not very nice.
