Thanks again for the report! I've committed the fix. Unfortunately,
unless you can compile yourself, you'll have to wait until the next
minor release for the fix. Given this is the .0 release of 12, and that
we already have a number of bugs to fix, I'm sure that won't be too far
away however.
If you want to work around the problem, you can, but it's not entirely
unproblematic: If, just when restarting, you set fsync to false, you'll
avoid the problem. But then you'd have to immediately re-enable
afterwards, and there's still a small data loss window. If however all
you want is to continue testing, fsync=off might be a reasonable
workaround.
Greetings,
Andres Freund
