Hm, yes, that could be improved. Perhaps:
This is required for a full backup of the cluster that is performed by pg_dump on the individual databases.
I don't see a problem with the existing wording. And as the OP hasn't really described what is confusing them it is difficult to contemplate a rewrite that would remove that confusion.
The sentence means that one must run pg_dumpall --globals-only (that is what "this" is referring to without doubt) and add the result to their backup (implied by the wording "necessary to fully backup"; this data is missing...) if their backup routine consists of backing up individual databases using the pg_dump command (exact wording).
If anything, whether one chooses to backup all databases in a cluster individually using pg_dump is immaterial. Any single database backed up using pg_dump is incomplete if it is restored into an empty cluster. One must also restore the globals into that cluster first to produce a valid restoration of that database. The existing wording implies as much (and we rightly assume restoration into a freshly initialized cluster) so still no word-smithing seems needed here.
