Magnus, Kevin:
Two things:
1) pg_receivexlog doesn't help for users who need to archive from the
master to cold storage (e.g. remote SAN, S3, whatever). So we're going
to still need an archive_command.
2) One reason users are using the "test -f" version of the archive
command is that we put it in the same postgresql.conf. I would suggest
that we don't put *any* archive command in the sample postgresql.conf,
since there is no command we can supply which isn't a potential foot-gun.
