Intellij IDEA failing with Postgres initialisation

When I am trying to run a test case from Intellij Idea I am getting following error on MAC OS X 

14:34:54.885 [main] INFO c.o.d.p.embedded.EmbeddedPostgres - Detected a Darwin x86_64 system

Same test case runs from outside of IDEA.

How should I get it working?
