Please how long does it take approximately to restore a 300 Go database using
pg_restore ? Are there benchmarks for that ?

That's not an exact science and this is really application-dependent.
For example the more your schema has index entries to rebuild at
restore the longer it would take. There are as well ways to tune the
server to perform a faster restore, by for example increasing
maintenance_work_mem, disabling autovacuum, moving wal_level to
minimum, etc.
