The big projects that embed jdbc drivers are not so many and probably
they are not releasing new versions only because of the dependencies
updates. And the 42.0.0 release is quite new.

As a side note: Hibernate 5.2 is officially Java8 only:
https://github.com/hibernate/hibernate-orm/wiki/Migration-Guide---5.2#move-to-java-8-for-baseline
And they soon will drop support for 5.1
(http://in.relation.to/2017/03/14/hibernate-orm-515-final-release/) when
5.3 is released. They've changed their policy last year and now you get
bug fixes only for the current and the previous release.
The upcoming version of Spring platform is also Java8:
https://github.com/spring-projects/spring-framework/wiki/What%27s-New-in-the-Spring-Framework#whats-new-in-spring-framework-5x
Spring 4.x is Java6, but Spring Boot requires Java7 and recommends
Java8:
http://docs.spring.io/spring-boot/docs/1.5.2.RELEASE/reference/htmlsingle/#getting-started-system-requirements

IMO these two will drive some migration effort to Java8.

Here the release tag seems OK:
http://search.maven.org/#artifactdetails|org.postgresql|postgresql|42.0.0.jre7|jar
Probably it's a bug in mvnrepository.com
