Are all of these languages purely preference, or are some better for writing DB functions than others.  Personally, although I write in PHP a great deal, I'd just get confused writing stored procs in PHP.  So I'll be writing my stored procs in plpgsql, just for the sake of my sanity more than any other reason.

I'm actually starting to write one of these for postgres, and apparently

There is at least one significant architectural issue here to deal with

Is it more desirable to have a single java vm and communicate via RPC,
or some other mechanism? ie sockets, or ? The alternative is to
instantiate a java vm for every connection, this could be onerous as
there would be considerable overhead for each java vm.     
I think anything other than a single jvm would be too much of a
performance hit.   
Ok, I tend to agree, so does anyone have any preferences for a protocol?
RMI, RPC, XML-RPC ? Anything better?
 
This will all go away as soon as java version 1.5 comes out but in the
meantime, what does everyone think

Comments are welcome.     
On platforms built with GCC3.2+, GCJ might be an alternative.   
There are numerous issues with classpath stuff with GCJ, but I'm
certainly willing to look at it.
