Supported Socks Proxy version

[raitmoon]

Which version of SOCKS proxy(4 or 5) does JDBC driver for PostgreSQL support?
What I want to do is connecting to PostgreSQL existing outside the company using JDBC driver with SOCKS proxy as belows:

Client Program -> Internal Network-> SOCKS proxy -> Internet -> PostgreSQL

JDBC Driver version: postgresql-42.2.14.jar
PostgreSQL version: 11

And network team need to know which version of SOCKS proxy is supported in advance for the scenario.
Sorry if this is not the right place to ask.
Any advice or suggestion is appreciated.

We don't "support" any. The driver connects using java sockets so if they work then the proxy should work.

Also 42.2.14 is horribly out of date

Thanks for your reply.

The version of JDBC driver is out of control for me at this moment..
