Some of the built-in features ( wal_compression ) have been there since 2016, and almost all backup tools do the WAL compression before taking it to the backup repository. They do a much better job than what was available in PostgreSQL (pglz). It uses more CPU and can affect the TPS for specific workloads and machine configuration.
