Hello Teodor,

I finally managed to perform this test on sparc v9 machine which is 64
bit big-endian architecture. I run pgbench script (see previous message)
with default_seed=123 on both x86-64 and sparc machines and visualized
the results. You can find them in the attached chart. Both images showed
the same distribution. So endianness isn't a concern here.

Thanks!
