You need to apply Robert's v10 version patches 0002, 0003 and 0004, before applying the lz4 patch(v8 version).
Please let me know if you still face any issues.
Thanks, Jeevan.
I tested —server-compression option using different other options of pg_basebackup, also checked -t/—server-compression from pg_basebackup of v15 will
throw an error if the server version is v14 or below. Things are looking good to me.
Two open issues - 1)lz4 value is missing for --server-compression in pg_basebackup --help 2)Error messages need to improve if using -t server with -z/-Z
