Is it possible to specify multi hosts dsn for connection pool?

Is it possible to connect to several hosts (one master and replicas) from ConnectionPool (interface like libpq provides)?

I mean the following: https://www.postgresql.org/docs/current/static/libpq-connect.html

# Read sessions
postgresql://host1:123,host2:456/somedb?target_session_attrs=any

# Read-write sessions
postgresql://host1:123,host2:456/somedb?target_session_attrs=read-write

I enumerate all postgresql hosts and in target_session_attrs parameter specify read-write if i need master.

Or i should create separate connection pools for master & replicas servers?

How that functionality (switching between hosts depending on target_session_attrs attrs, re-connecting on master switch) can be implemented in asyncpg?

Comienza revisando la interfaz ConnectionPool de asyncpg y la documentación enlazada de PostgreSQL libpq sobre DSN multi-host y target_session_attrs. El issue no menciona archivos fuente ni tests; se consideraría completado con un soporte claro para la selección de múltiples hosts y la reconexión, o con una alternativa documentada que use pools separados.
