Add:

>
> * Allow control over which tables are WAL-logged
>
>   Allow tables to bypass WAL writes and just fsync() dirty pages on
>   commit.  To do this, only a single writer can modify the table, and
>   writes must happen only on new pages.  Readers can continue accessing
>   the table. Another option is to avoid transaction logging entirely
>   and truncate or drop the table on crash recovery.  These should be
>   implemented using ALTER TABLE, e.g. ALTER TABLE PERSISTENCE [ DROP |
>   TRUNCATE | STABLE | DEFAULT ].  [wallog]
