Log Message:
-----------
Introduce AutoSave = SERVER functionality

If the Postgres server (11.0 and above) supports transaction
level rollback functionality, then instead of using JDBC side
manual savepoints in AutoSave=ALWAYS mode, use the server
side implementation. This patch introduces a new option for
AutoSave: SERVER for the same. Patch also includes relevant
test cases (BatchAutoSaveTest.java) and documentation changes

Log Message:
-----------
Make autosave=server missing server support error more specific

autosave=server would report "Transaction rollback statements are not supported"
even for completely unrelated connection errors like

org.postgresql.util.PSQLException: Transaction rollback statements are not supported
...
Caused by: org.postgresql.util.PSQLException: FATAL: role "test" does not exist
...

Now it'll properly re-throw for other cases.
