Agreed. I thought last night about the sentence and realized when we
say pg_global is used for shared system catalogs, we are not saying
other object can't also be put there, so the "only" seemed required, and
once I added that, the second sentence fragment seemed unnecessary.

Plus, this report is from three years ago and I haven't seen any other
reports since then.

I also prefer manage-ag.sgml because we already talk about pg_global
there, and hopefully users of GUC tablespaces and CREATE TABLE will see
it there, or at least look for it when they get the error on creation.
