Possible to set `application_name` for client connection?

Is it possible to set `application_name` i.e. https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS:

```
postgresql://other@localhost/otherdb?connect_timeout=10&application_name=myapp
postgresql://host1:123,host2:456/somedb?target_session_attrs=any&application_name=myapp
```
