Most cloud servers come preconfigured with some variation of either
the "LAMP" or "LAPP" stack: i.e. Linux, Apache, MySQL or Postgresql,
PHP or Python.

There needs to be a compelling *application* reason to install
something else: a JVM (or Apache-Tomcat vs regular Apache),
Ruby/Rails, Groovy/Grails, etc.

Absolutely.  The DBMS is (programming) language neutral - the only
requirement is that a client speak the wire protocol.  That can be
done natively, or via a library/driver.

Not really sure what you're asking.  The application running under
HHVM or node.js is completely separate from Postgresql.

Both PHP and Javascript (generically and for node.js specifically)
have libraries for Postgresql.
