For most commands, it does not matter whether you issue them from the primary database or the proxy database; only the primary database is updated. These commands cannot be issued from within the proxy database:
create or drop procedure
create or drop view
create or drop trigger
create or drop rule
create or drop default
You must run dump and load database commands from the primary companion. If you issue these commands from the proxy database, they will update only the proxy database; they do not update the primary companion.
