Interestingly it also logs a variety of things that worked while those were logged, maybe it only happened for the /tmp filesystem and not / ... apparently postgresql was still writing stuff on the disk in that period, so I'd guess this only happened on /tmp This is square in the middle of the reported blocks: Oct 20 17:52:00 pixometerstag04 postgres[1008]: user=,db= LOG: checkpoint complete: wrote 0 buffers (0.0%); 0 transaction log file(s) added, 0 removed, 0 recycled; write=0.004 s, sync=0.001 s, total=0.018 s; sync fi> -- You may reply to this email to add a comment.
