​Not our (PostgreSQL's) bug...its JDBC's.

We are well within our rights to remove configuration parameters in new
versions.

If you do post an issue against the JDBC driver it would be nice to know
why you are trying to connect to a version 9.5 server using an outdated
protocol version.

This has already come up and a PR was opened:

https://github.com/pgjdbc/pgjdbc/pull/581

See additional discussion therein.

In addition to GitHub JDBC-related discussions also happen on:
