Could it be possible to see a backtrace of the crash? There is
nothing we can really do without any hint. If you can send a
self-contained test case which allows to reproduce the problem, that's
even better. Please note that unlogged tables are reinitialized after
a crash at the beginning of recovery. That's their design.
