This PR registers a custom driver name for pq, per lib/pq#470 (comment), and uses it to override the default dialer with one that can transparently handle socks proxy configuration through environment variables.
The environment variable is named
ALL_PROXY
(all_proxy
also works) and has the formatsocks5[h]://[<socks-user>:<socks-password>@]<socks-host>[:<socks-port>]
There is also support for a
NO_PROXY
/no_proxy
environment variable which lists hostnames, IP addresses, CIDR blocks, and wildcard domain names which should not go through the proxy.
