Maybe I'm missing something, but I did check the wal_compression thread
[1], and I don't think it was rejected at all. I think people agree with
the proposa to change what 'on' means, depending on whether lz4/zstd is
supported by the build. And I agree with that plan, so let me comment on
that thread.
