It will make it to the other platforms eventually, I hope.  It's a
shame that Sun's "write once, compile once, run everywhere" promise is
just marketing to some extent.

pl/pgsql is a great language, I agree.  However, java has some
tremendous advantages.  The big one is its classes.  I needed to do
some DES encryption within the PG database.  Well, there's no DES
function in PG, or in pl/pgsql, so I had to write it as a C function
and then link it in.  Sure, that works, but the point is, if we had
pl/java, I would just call java.security.encryption.des() (or whatever
it is) and it would be there.  Right now I need to do some public key
stuff.  I could try to link that all in in C, but that would be a huge
pain.  The java standard classes do just about everything.  pl/pgsql
will never come close to that.

Also, java is object oriented and more convenient for writing larger
things.
