Shouldn't pg_dump do this, and perhaps by default?
If I restore a dump into another instance, I need to upgrade all my extensions to that installations's versions, no? That's not particular to pg_upgrade.
Sure, there's an argument to be made for that. But pg_dump (or in this case, it would more be pg_restore I guess) also doesn't run ANALYZE or generate a script to do that, does it? ISTM that we have already decided that pg_upgrade has a different requirement on providing those things, whereas pg_dump/pg_restore is more of a low-level tool where people have to figure more things out themselves.
