Fix parallel safety markings for pg_start_backup.
Commit7117685 made pg_start_backupparallel-restricted rather than parallel-safe, because it now relieson backend-private state that won't be synchronized with the parallelworker. However, it didn't update pg_proc.h. Separately, AndreasKarlsson observed that system_views.sql neglected to reiterate theparallel-safety markings whe redefining various functions, includingthis one; so add a PARALLEL RESTRICTED declaration there to matchthe new value in pg_proc.h.
