The source and destination servers have to be the same major PG release,
same architecture (no 32-bit vs 64-bit for instance), and built with the
same configure options. OS per se shouldn't matter, but you could
easily get burnt on configure options if you use binaries obtained from
different packagers. Compare pg_config output or check the fields
listed by pg_controldata.
