Hmm. Grouping these together makes sense for the user. One choice
that we have here is to drop the short option, and just use a long
one. What I think is important for the user when it comes to this
option is the consistency of its naming across all the tools
supporting it. pg_dump and pg_basebackup, where we could plug LZ4,
already use most of the short options you could use for pg_receivewal,
having only a long one gives a bit more flexibility.
