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. Such “torn pages” are corruptions from the database point of view. This is generally referred to as “ partial page writes ” or “ torn pages.” Lz4 is a good example.
