That's poor advice. Use a database with checksums enabled like DB2, Oracle, Postgres, SQL Server or SQLite with the Checksum VFS Shim. TFA recommends the latter for good reason.

Running a database on ZFS results in reduced throughput, while Btrfs and Bcachefs are outright performance disasters. [1][2]
