And one doesn't want to set archive_command w/o doing some kind of setup
work on the server in question, perhaps setting up SSH keys or putting a
decent shell script in place to be called from archive_command. That's
part of my issue w/ this- the parameters which can't be set up correctly
through sole use of "ALTER SYSTEM" should be excluded from it and
instead set up through a config file.

Thanks,

Stephen
