+1 from me, too.

The problem with the status quo (after Peter's commit) is that there's
now nothing at all to identify the logical replication launcher, apart
from the wait_event field, which is likely to be LogicalLauncherMain
fairly often if you've got the launcher.  I don't personally see why
we can't simply adopt Tom's original proposal of setting the query
string to something like "<logical replication launcher>" which, while
maybe not as elegant as providing some way to override the
backend_type field, would be almost no work and substantially better
for v10 than what we've got now.
