     LOG=0 means the transaction log is disabled completely (fastest; for loading a database).
     LOG=1 means the transaction log is enabled, but FileDescriptor.sync is disabled (if no protection against power failure is required).
     LOG=2 is the default (transaction log is enabled, FileDescriptor.sync for each checkpoint).
