Description:

Hello there,

I don't know if it's me but I find this sentence quite confusing in its
current wording:
All slots on the old cluster must be usable, i.e., there are no slots whose
pg_replication_slots.conflicting is not true.

The prerequisite is that no replication slot has conflicting=true right?
So this sentence (the i.e. part) suggests the opposite, as per my
understanding.

Here is the link (29.13.1):

Thanks.
Regards,
