Could you check whether the server is crashing ?
If you run "ps -fu postgres", you can compare the start time ("STIME") of the
postmaster parent process with that of the persistent, auxilliary, child
processes like the checkpointer. If there was a crash, the checkpointer will
have restarted more recently than the parent process.
The SQL version of that is like:
SELECT date_trunc('second', pg_postmaster_start_time() - backend_start) FROM pg_stat_activity ORDER BY 1 DESC LIMIT 1;
