* Allow buffered WAL writes and fsync
Instead of guaranteeing recovery of all committed transactions, this
would provide improved performance by delaying WAL writes and fsync

committed transactions but still be consistent. We could perhaps
remove the 'fsync' parameter (which results in an an inconsistent
database) in favor of this capability.
