In this case you can choose a filesystem with lower overhead. For
example with WAL you don't need a journalling filesystem at all, so
using ext2 is not a bad idea. For Pg data files, you need journalling
of metadata only, not of data; the latter is provided by WAL. So you
can mount the data filesystem with the option data=writeback.
