Re: Re: transaction lost when delete clog file after normal shutdown

[章晨曦@易景科技]

S1:
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.


S2:
When database crashed, and  clog file missing, when database restart, 
it will try to recover. And everything is ok


So I think we may improve the database more reliable in some scenarios, e.g. 
Only clog file corrupted or missing, like S1

&gt; we simulate crash and clog file corrupt (delete the clog file)

Clog file cannot disappear as a result of a crash. What makes you think 
otherwise?
