OK, the following was the answer from you.

I appreciate your reply, but please
don't be such instructive except on postgresql.

In fact , I didn't get a satisfactory answer from you because
"Sorry, you ask more questions that I have time to answer right now."

So I tried to make my questions less and simpler as follows:
- Does Vacuum delete the old clog files?
- Can we controll the maximum number of the clog files?
- When, or in what case is a new clog file produced?
- Is there a mechanism that the clog files are recycled? If there is ,
what is the mechanism?

#The version of my postgresql is 8.1.
I have encountered an issue that there are too many
clog file under the .../pg_clog/ directory. Some of them
were even produced one month ago.

Thanks
Duan
