I think we need something better than that. We shouldn't be shooting at
pids in a production database: we may get it wrong and take something
else down instead.

We need a graceful termination of replication and an immediate one.
There may be other things we need to add later, so a specific command
will be better and allow us to produce messages like "replication isn't
running" if used inappropriately.
