What's "global"?  A maybe-useful flag would be telling that a table is
shared.  Is that it?  Mind you, it's not useful to me because I know
which tables are shared, but I guess for someone not so familiar with
the catalogs it could have some use.

The OIDs may be useful to people inspecting pg_depend, for example; but
then, it's foolish not to be using regclass in that case.

Whether a table is "bootstrap" or not doesn't seem useful to me.
