Michael, what you are missing is that while Linux is the same, a) the
maturity of the libraries eg C library, other libraries you link
against may not be as thoroughly debugged b) not as many people use
Linux PPC thus there are not as many "eyes" looking at it.
the very first thing I would do would be to run "ldd" on the Postgres
binaries, and write down which version of each library is used. Then
check against an equivalent Intel version. If they are different, try
to get the exact same version that is installed on Intel installed
under PPC. Read up on how to use LD_LIBRARY_PATH so that you can
easily test changes (man ldconfig should tell you this.).
