Please refer to this scenario , where --server-compression is only
compressing
base backup into lz4 format but not pg_wal directory
[edb(at)centos7tushar bin]$ ./pg_basebackup -Ft --server-compression=lz4
-Xstream -D foo
[edb(at)centos7tushar bin]$ ls foo
backup_manifest base.tar.lz4 pg_wal.tar
this same is valid for gzip as well if server-compression is set to gzip
edb(at)centos7tushar bin]$ ./pg_basebackup -Ft --server-compression=gzip4
-Xstream -D foo1
[edb(at)centos7tushar bin]$ ls foo1
backup_manifest base.tar.gz pg_wal.tar
if this scenario is valid then both the folders format should be in lz4
format otherwise we should
get an error something like - not a valid option ?
