&gt; When database normal shutdown, and clog file missing, the database cannot 
restart. And if make a zero clog file, database started but may cause 
transactions lost.

&gt; S2:
&gt; When database crashed, and&nbsp; clog file missing, when database restart, 
it will try to recover. And everything is ok
&gt; 
&gt; So I think we may improve the database more reliable in some scenarios, 
e.g. Only clog file corrupted or missing, like S1

I still do not get it. Why clog file would be missing?
