Log Message:
-----------
Add:

>
> * 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
>   so an abrupt operating system restart might lose a few seconds of
>   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.
