The problem here is that making some feature optional must be clearly
stated, preferably in the bundle name. I'd expect postgresql jar taken from
Fedora distribution behave the same as postgresql jar taken from the
official web site. if you change it - tell in bold in the description or
name it postgresql-no-osgi.jar.

E.g. if look here:
http://mvnrepository.com/artifact/org.hibernate/hibernate-osgi/4.3.5.Final
you will see hibernate-osgi depends on org.osgi artifact.
And in Fedora:
https://www.rpmfind.net/linux/RPM/fedora/devel/rawhide/s390/h/hibernate-osgi-4.3.5-6.fc23.noarch.html
this dependency is provided by felix:
https://www.rpmfind.net/linux/rpm2html/search.php?query=mvn(org.osgi%3Aorg.osgi.core)

I don't thy to argue bundling, it's just apple must be apple. If you change
it - you reflect in the name (see above).
And I'd say OSGI problem must be thought globally in OSS, not only for
PostgreSQL. Basically, as I see it, current OSGI support is stuck at
version provided by felix that is outdated (dunno why, may be felix guys
just switched to org.osgi artifact). That's why a lot of projects dependent
on it are outdated too (e.g. hibernate noted above is already at 5.0.7,
4.3.5 was release in April 2014). And it does not mean OSGI is not used in
OSS world.
