I think you made that clear :-)

However, it doesn't seem to work like that. Even with ONLY either
unlogged (the global ones) and temprorary tables (the local ones), the
system still produces a huge amount of WAL/checkpoint writes. In fact,
the "wal-writer" and "checkpoint" processes are the biggest writers in
the system. checkpoint process uses up to 9GB of Ram and wal produces
more writes than any other process.
