You mean, the double I/O of writing the block to the WAL and data file?
(We'd still have to write the changed columns or whatever to the WAL,
right?)
I'd just add an option to turn it off. If you need it, you need it;
there's no way around that except to buy hardware that is really going
to guarantee your writes (which then means you don't need it).
