What does `ldd /usr/local/pgsql/lib/libchmoogle.so` say? What about when
run under the PostgreSQL user account?
You may need to set LD_LIBRARY_PATH in the Pg startup script, or modify
ld.so.conf, or re-build your extension with rpath linking enabled.
As for why it worked with 8.4 - I expect you either altered
LD_LIBRARY_PATH in the 8.4 startup scripts, or maybe the 8.4 version of
the extension was built with -Wl,-rpath so the paths to required
libraries were embedded into the extension library.
