I'm not looking into the messages, I know their language dependent. I
even added two or three new error messages, but only in English.

I'm looking for either specific error codes, range of error codes, or
some class extending PSQLException that will just indicate that this
connection is no longer useful. For example, if an I/O error occurs,
there's no ReadyForQuery reply, there's garbled response, etc.

PM: There are not error codes available. Also, there's nothing extending
PSQLException (yet), but there's no reason not to extend it.
