Providing them as a contrib/ package will allow you to provide the
*full* complement of cross-type conversion and operator functions
without worrying about bloat. Tom Lane has shown how to use entry points
on shared libraries to start us thinking about how to provide better
package integration, which should allow us to reduce the distinction
between contrib/ and standard features.
This would be a great package to develop these additional package
support features for 7.2 (hint hint ;)
