So, how about: "All slots on the old cluster must be usable, i.e.,
their pg_replication_slots.conflicting is false."?

That works.

Then we’d also change:

The new cluster must not have permanent logical slots, i.e., there must be no slots where pg_replication_slots.temporary is false.

To be:

“The new cluster is only permitted to have temporary logical slots, i.e., ones where pg_replication_slots.temporary is true.”

We could make it mirror the above one more closely, but as the former mentions the old cluster and the later the new one, I kinda like the different flow, less likely to skim over it.
