I think you misunderstood - I'm suggesting not only to use with-lz4 (which was
always true since 93d973494), but to change pg_dump -Fc and -Fd to use LZ4 by
default (the same as I suggested for toast_compression, wal_compression, and
again in last year's patch to add zstd compression to pg_dump, for which
postgres was not ready).
