Morph pg_replication_slots.min_safe_lsn to safe_wal_size
The previous definition of the column was almost universally disliked,
so provide this updated definition which is more useful for monitoring
purposes: a large positive value is good, while zero or a negative value
means danger. This should be operationally more convenient.
Backpatch to 13, where the new column to pg_replication_slots (and the
feature it represents) were added.
