Yeah, I'm afraid that these names are not as well standardized as Peter
probably wishes they were.  Also, I'd just as soon not move/rename things
that don't really need it.  If, for example, we decide to move
postgresql.conf to etc/postgresql.conf, that is going to break a metric
ton of stuff that doesn't need to get broken AFAICS.
