That's because "hot_standby = on" by default from v10 on.
You could change the configuration and set it to "off",
then PostgreSQL will continue to work as before.
The alternative way is running this after you connect:
SELECT pg_is_in_recovery();
If that returns TRUE, recovery is not done yet.
Back out, wait a while, then try again.
