I thought this part was odd -- I mean, why is SysLogger_Start() being
called if the collector is not enabled? Turns out we do it and return
early if not enabled. But not in all cases -- there is one callsite in
postmaster.c that avoids the call if the collector is disabled. That
needs to be changed if we want this to work reliably.
I don't think the "abstract names" stuff is an improvement (just look at
the quoting mess in ConfigureNamesString). I think we should do without
that; at least as part of this patch. If you think there's code that
can get better because of the idea, let's see it.
