Author could have started by surveying current state of art instead of just falsely assuming that DB devs have just been resting on the laurels for past decades. If you want to see (relational) DB for SSD just check out stuff like myrocks on zenfs+; it's pretty impressive stuff.

bcachefs's btree still beats the pants off of the entire rocksdb lineage :)

anything like this, but for postgres?

actually, is it even possible to write a new db engine for postgres? like mysql has innodb, myisam, etc

There has also been some significant academic study of DBMS design for persistent memory - which SSD technology can serve as (e.g. as NVDIMMs or abstractly) : Think of no distinction between primary and secondary storage, RAM and disk - there's just a huge amount of not-terribly-fast memory; and whatever you write to memory never goes away. It's an interesting model.

But then how would they have anything to do?
