Yes.  It will go through the normal DB upgrade the first time you run 
mythtv-setup.

Once you reconfigure, it will be exactly the same as the database /and/ 
data you would have had if your 0.21-fixes DB schema weren't 
corrupt--except maybe a bit cleaner (as it will get rid of some old 
garbage you may have had for old hosts you may have run.
