That only means that the output TAR file will be compressed, it has
nothing to do with the data transfered from the server.

If you want to compress the data sent over the network, use
pg_basebackup over an SSL connection with SSL compression enabled.

But ssl compression is disabled by default on most systems, and not even supported at all on many without doing a custom compilation of the ssl library.
