TABLE METADATA setting saved in location?

Hi,
i need help in knowing -
suppose in admin setting, in "TABLE METADATA" tab.. i am changing some typecast of columns in my local system. where do these changes get saved in local.
like we have -
metabase.db.mv.db
metabase.db.trace.db

thanks,

you need to get away now from H2... you'll end up with corruption very soon

if you used postgres, that's saved in the fields table
