pg_promote not marked as parallel-restricted in pg_proc.dat

Hi all,

It looks that I forgot to mark pg_promote as parallel-restricted in
1007465 in pg_proc.dat.  It seems to me that this is not a huge issue as
system_views.sql redefines the function for its default values and
enforces parallel-restricted, but let's be right from the start.

Attached is a patch to fix that.  Any comments or objections?  Please
note that the catalog version bump is included as a personal reminder..

Thanks,
