+Now we can connect to proxy a.k.a. router and play with it:

+```bash

+psql (13.3, server 9.6.22)
+Type "help" for help.

+```
+
+> NOTICE messages are disabled by default, specify `show_notice_messages` setting in the router config to enable them
+
+You could check now that each shard has only one record:
+
+```bash
+demo=> SELECT * FROM orders WHERE id = 777;
+NOTICE: send query to shard(s) : shard01
+  id  | customer_id | order_data 
+------+-------------+--------------

+(1 row)
+
+SPQR can handle such queries as `SELECT * FROM table` but we don't recommend using it. This feature is implemented in a non-transactional way.
+
+```bash
+demo=> SELECT * FROM orders WHERE id = 777;
+NOTICE: send query to shard(s) : shard01
+  id  | customer_id | order_data
