Yes. I believe creating it is fairly important :-) Seriously, the 2.16.2 
shadowdb is a bit of a hack, and you shouldn't need it unless your 
database is _very_ large (of the public Bugzillas, only b.m.o. uses it.)

The new shadowdb in 2.17 uses MySQL replication, which is far better 
suited to the job.
