Interesting approach.  The other person that posted recently was going
to run Java as a separate daemon, since the idea of linking postgres
with the JVM was causing loud gagging sounds among the members of this
list (for reasons I agree with).

Are you talking about Java compiled to native code rather than
bytecode?  I know GCJ can do that and it would seem to be a better way
to do this (since you can already link in native compiled C
libraries).  

The other thing to be aware of is that, if GCJ requires linking with
thread libraries, you may have some problems, since the PG backend
itself is not threaded--I'm not sure I'd want a threaded library call
running in a non-thread-aware app.

Have fun!   Sounds a neat idea.
