Could you add a test case?

@bpd0018 , there might easily be `PGProperty.PROTOCOL_VERSION.set(properties, 3)` usages in the wild, so we cannot just remove `PROTOCOL_VERSION` property.

That is I would prefer to just document the current state of `protocolVersion` (== only `3` is supported, etc) and live it as is.

I expect the majority of the cases would be plain old usages that do not require retrieval of parameters. Thus it looks we should favor an implementation that decodes parameter...

Just in case, the test is locale-dependent. That is not good. `до н.э.` is a Russian for `BC` ``` org.junit.ComparisonFailure: LocalDateTime=-1996-06-30T23:59:59.999999, with TimeZone.default=Z, setObject(int, Object) Expected :1997-06-30 23:59:59.999999 до н.э....

@kdubb , technically speaking, the test was disturbed in https://github.com/pgjdbc/pgjdbc/pull/1388/files#diff-8b723c347b2146e27df7b1aa5f76e800L317 As far as I understand, when using ISO, PostgreSQL never prints locale-dependent BC.

Unfortunately, I do not understand the nature of the issue yet. I would review this sometime later. The old behavior was there for quite some time, so users might already...
