Impossible, IMHO. The entire idea of the combined writes (FW=OFF + MaxUnflushed* set up) is that pages are written into the file system cache (and it doesn't not guarantee any disk writes) and then flushed as a batch (and it doesn't guarantee the write order). So the OS plays against us here. The only way to guarantee ordered writes is to flush individual pages and this is what FW=ON does. > or to have something like in PG > http://www.postgresql.org/docs/9.1/static/wal-async-commit.html > (I know we don't have WAL) I don't see how it could be done without WAL.
