+The order of rules in `pg_hba.conf` matters.
+<!--more-->
+
+Trying to connect to postgresql database with a standard user fails with `psql: FATAL: Peer authentication failed fr user "user1"`.
+
+The second line of `pg_hba.conf` makes your connection attempt fail:
+```
+local   all     all     peer
+```
+
+The order of rules matter. If the first one that matches the access method, username, database name and source IP range fails, there will be no second attempt. So either remove this line, your place your rule above this one.
