I just upgraded from 7.4.8 (same format as 7.4.1) to 8.0.3 using the
pg_dump/pg_restore method described in the documentation, and I did not
encounter any issues. Although my system did not change, I don't think
you'll encounter any issues due to a different operating system since the
dump is just a single regular file containing all necessary information to
restore your database(s), its interpretation is up to pg_restore and not
your OS.
Hope this helps,
Kilian
