pgjdbc 42.1.2 released

Hi,

The JDBC group is proud to release the latest driver (42.1.2).

Notable changes include:
* Better logic for returning keyword detection. Previously, pgjdbc could be
defeated by column names that contain returning, so pgjdbc failed to
"return generated keys" as it considered statement as already having
returning keyword PR#824
* Replication API: fix issue #834 setting statusIntervalUpdate causes high
CPU load PR#835
* perf: use server-prepared statements for batch inserts when
prepareThreshold>0. Note: this enables batch to use server-prepared from
the first executeBatch() execution (previously it waited for
prepareThreshold executeBatch() calls)

Thanks everybody.

Dave, would you please update the site?

The subsequent release will include SCRAM client (the implementation is
jre8-specific), so the next version is 42.2.0
