Checking the git history, this was fixed in f560209c6, which also
included some other mostly-cosmetic cleanup. I'm inclined to
propose back-patching that whole commit, rather than allowing the
code in exec_replication_command() to diverge in different branches.
It looks like it applies cleanly as far back as v10. Maybe something
could be done for 9.6 as well, but since that branch is so close to
EOL, I doubt it's worth spending extra effort on it.
