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
