Curious, when it comes to "traditional" filesystems, why ext4 and not
xfs ? AFAIK the legacy issues associated with xfs are long gone ?
XFS is not being very actively developed any more. Ext4 is being
actively developed and it has some features to help with SSD space
allocation. Phoronix has some very useful benchmarks:

Ext4 is much better than XFS with SQLite tests and almost equal with
MariaDB test. PostgreSQL is a relational database (let's forget the
object part for now) and the IO patterns will be similar to SQLite and
MariaDB. That benchmark is brand new, done on the kernel 5.14. Of
course, the only guarantee is doing your own benchmark, with your own
application.
RedHat and Oracle are mostly maintaining XFS updates, and I didn't see
anything saying it's not mainained actively,
especially when they offering many solutions with XFS as default
