First, I assume that our patchset is used with a filesystem that supports
direct access (DAX) feature, and I test it with ext4 on Linux. You can cd
into pg_wal directory created by initdb -X pg_wal on such a filesystem, and
ls WAL segment files managed by PMDK at runtime.
For each PostgreSQL-specific tool, perhaps yes, but I have not tested yet.
At least, pg_waldump looks working as before.
