Won't we have many more options in this area, i.e. increasing performance
while maintaining on-disk data integrity, once WAL is implemented?

snapshot+WAL = your database so in theory -F on tables and
the transaction log would be safe as long as you have a snapshot and
as long as the WAL is being fsync'd and you have the disk space to
hold the WAL until you update your snapshot, no?
