connect through socks5 proxy

Nobody has claimed this yet.

I would like to use asyncpg through a socks 5 proxy. I need this because the postgresql instances are running inside a docker overlay network (swarm). The IP addresses of the servers are not fixed, and it is not possible to access them directly.

If I had a single postgres server, then it would not be a problem to manually create a tunnel. But I need to connect to several different servers, and their ip addresses are changing. Manually creating a bunch of host aliases and creating multiple tunnels is just not practical.

Would it be possible to add a layer that would allow me to add my own callback for creating the TCP socket for a given host name + port pair?

The issue names no files or tests. Start by tracing asyncpg connection setup and the TCP socket creation path for a host-and-port pair, then determine how a user-supplied callback could support SOCKS5 connections to changing PostgreSQL server addresses. Done means the requested connection layer is designed and its behavior is validated.
