The "solution" is that extensions must only link against the handful of 
libraries in the URE interface (basically cppu, cppuhelper, sal, 
salhelper) and not against any others provided by LO.  Everything else 
is not supported and is an error.

The best fix would probably be to change postgresql-sdbc.oxt from a 
bundled extension into an -- optionally installable, but "proper" -- 
part of the installation.

A workaround hack for Linux would indeed be to modify RPATH, see 
(RUNPATH is link-time only, btw.).
