In principle yes, since the compatibility is controlled by a protocol 
version that is separate from the release version.

Note, however, that 2.3.1 is a bug-fix release on top of 2.3.0, and 
there is now also a 2.3.2.  Just like with PostgreSQL core, it's 
advisable to use the latest minor release, and if anything goes wrong, 
the first piece of advice would likely be to upgrade.
