There's a very good reason for not recommending pg_dump in this context:
it won't dump everything. Yeah, if you know what you're doing, you might
use per-database pg_dump runs plus pg_dumpall -g to catch the roles etc,
but we're not going to try to wedge all that info into one or two
sentences of release-note boilerplate. If you can get that right then
you don't need the release notes to remind you anyway. If you aren't
likely to get it right then the release notes would do you no service
by suggesting it.
I'm not sure what "many limitations" you think pg_dumpall has that pg_dump
I do think that it might be time to reword this to recommend pg_upgrade
first, though. ISTM that the current wording dates from when pg_upgrade
could charitably be described as experimental.
