IIUC, Bruce's complaint is that the name is too generic (which I agree
with).  Given the stated functionality:

it seems like the name ought to have some connection to
synchronization.  Perhaps something like "synchronized_standby_slots"?

I haven't read the patch, so I don't know if this name is especially
on-point.  But "standby_slot_names" seems completely unhelpful, as
a server could well have slots that are for standbys but are not to
be included in this list.
