Could you post your fix here, so we can review it, and it can be applied
to the CVS eventually?

How did you install your PostgreSQL and your gcc toolchain? From the
same DVD? Then they all should be the same platform, at least, if SuSE
didn't break it.

You don't need a 32-bit kernel, an 64-bit kernel for running 32-bit apps
is just fine (and might even perform better than a 32-bit kernel on some
configurations). You can also have a mixture of both 32-bit and 64-bit
applications installed on a 64-bit kernel. This leads to having some
libs available in both 32-bit and 64-bit, but apart from some wasted
disk space and RAM, it doesn't hurt.

But you have to make sure that PostgreSQL, pljava and the JDK all are
the the same "bit-number".

The "gcc 64 bit lib error related to an incompatible libjvm.so (in the
i386 directory)" you quoted in your previous message made me think that
PostgreSQL and PLJava seem to be compiled in 64-bit, whereas the JDK is
in 32-bit.


HTH,
Markus
