You can create the replication slots manually with
pg_create_physical_replication_slot() any time.
However, unless you are very brave and know what you are doing, I'd
recommend using pg_basebackup to setup a standby, not rsync. You can
even use the -C and -S options of pg_basebackup to create the slots
for you, and many other pg_basebackup's nice options.
