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?

Inizia esaminando l’interfaccia ConnectionPool di asyncpg e la documentazione collegata di PostgreSQL libpq sui DSN multi-host e target_session_attrs. L’issue non indica file sorgente né test; il lavoro sarebbe completo con un supporto chiaro per la selezione di più host e la riconnessione, oppure con un’alternativa documentata che utilizzi pool separati.
