Thank you for your reply , Why did I come up with this idea? When I suggested changing `wal_compression on` to ZSTD or LZ4, Wasn’t accepted. So I wondered if it could be implemented internally. In any case, it can’t compete with LZ4, so I don’t think it’s worth investing effort into improving PG-LZ. Setting LZ4 or ZSTD as the default is the best option.
