I am afraid you are going to have to use pg_dumpall --globals-only and
then loop each database running pg_dump with the flags you need.

The -t/-n flags were not added to pg_dumpall on the assumption that you
wouldn't be including/exclusing the same schemas/tables on every
database, so you have to do it per-database.
