Please, try

mkdir /tmp/wal
initdb /tmp/pgsql
pg_ctl -D /tmp/pgsql -l /tmp/logfile start
psql postgres
SELECT pg_create_physical_replication_slot('replica1');
CREATE ROLE repluser WITH LOGIN REPLICATION PASSWORD 'replpass';
\q

synchronous_commit = on
synchronous_standby_names = 'replica1'

pg_ctl -D /tmp/pgsql -l /tmp/logfile restart
pg_receivewal -D /tmp/wal -S replica1 --synchronous -h localhost -p 5432 
-U repluser -W
psql -c 'SELECT * FROM pg_stat_replication;' postgres
psql -c 'SELECT * FROM pg_replication_slots;' postgres
psql -c 'CREATE DATABASE test' postgres

In what scenarios do you see 'on' working ?
