I have applied the attached patch to show examples of using rsync on
PGDATA and tablespaces, documented that rsync is only useful when in
link mode, and explained more clearly how rsync handles links. You can
see the results here:
http://momjian.us/pgsql_docs/pgupgrade.html
Any more improvements?
Very nice!
For sake of completeness I think an example of running rsync when
having pg_wal located outside the data directories would be helpful. Especially
an example upgrading from 9.6 to 10 because of the name-change of pg_xlog ->
pg_wal.
