The description of this GUC provides a list of the situations where full-page writes are generated. However, it is not completely exact, mentioning only the cases where full_page_writes=on or base backups. It is possible to generate full-page writes in more situations than these two, making the description confusing as it implies that no other cases exist. The description is slightly reworded to take into account that other cases are possible, without mentioning them directly to minimize the maintenance burden should FPWs be generated in more contexts in the future.
