Tablespace size in TB

Hi,

Postgres = Version 13

OS=Linux Redhat version 8

Our team is using a single tablespace for the whole database. Its size is
more than 13TB. I am from an Oracle background and want to suggest that
they split the data in multiple tablespaces. It will not only improve the
performance & reduce the backup time.

But I did not find any Postgres best practice or blog, to show as a
reference.
