There is a standard for the SQL integration of a "java" language, and I
don't see why there can't be multiple implementations of that same
specification. It in fact appears that there are. Of course we would
not want the programming interfaces to differ, but they don't have to.

Hmm, Thomas Hallgren sent in a template using "java" as name and you
answered "OK", so we're already there if it's already committed.

There is no hope of that, but a mere recompilation does not change the
validator or the schema or any other property that may be under
consideration. The current code will force a *version* upgrade of all
PLs with every PostgreSQL upgrade. I need to download new code and
deal with it. That is currently not required. And considering the
general breakage of PLs out there, I don't think it's acceptable to
require it. What if the new PL/R also requires a new R? What if the
new R requires a new GCC? We don't know that, we can't control that,
we should not interfere in that. I'm not making this up; these
problems are real (although not necessarily in PL/R).
