Urgh. If you shut down the postmaster cleanly before backing up, then
you don't really need pg_xlog --- running pg_resetxlog will get you out
of the above problem. However, if you did not save pg_clog then I fear
you are well and truly screwed.
How long ago was your last complete (database-wide) VACUUM? If it was
just before shutdown then you may be able to achieve some semblance of
a consistent database, but if it was awhile ago then you do not have
a database but just a pile of bits :-(
