MySQL dump restore - how to retain comments
OMG I know your problem !!!

Here is the problem: The mysql client filters out comments.

-c, --comments      Preserve comments. Send comments to the server. The
                    default is --skip-comments (discard comments), enable
                    with --comments.


Just load the mysqldump file like this:

mysql -u... -p... --comments &lt; dumpfile.sql


Give it a Try !!!
