In theory if you resurrect the schema exactly as it was, and then copy
the old files in place, you *may* be able to read them. However, you're
going to have trouble with non-existing XIDs. Yo umight be able to
recreate the XLOG/CLOGs but the whether it's going to be consistant is
anyones guess...
Have a nice day,
