I have a database that's about 2TB in size, and I want to place the database files in a separate mount point(PGDATA) and the log files in a different mount point(PG_WAL). What's your take on this?.

Take a look at https://wiki.postgresql.org/wiki/Installation_and_Administration_Best_practices

Essentially, yes, you will want your WAL and data stored on different devices (or the very least, different partitions).

Is that recommendation still valid?  After all, that was written when 15 years old Sun Studio 12 was still pertinent.  Times have changed since then.  Disks are much, much bigger.
