Fairly similar? The one is a Linux kernel with a Linux environment,
the other is a Mach kernel with a mostly BSD environment. I think you
can expect all kinds of fun with line-ending styles (Mac traditionally
used \r, Linux/Unix uses \n), locale handling differences, different
time zone handling, different page sizes, different floating point
sizes, etc.
You're in for an interesting experiment, if you manage to get the DB
running at all. If you do I'd thoroughly check for any data-
misinterpretation. I suggest doing a diff on text-dumps from both
databases and see if there are any differences. I'd still not trust
the data in it afterwards, but whether that matters depends on what
you intend to use it for.
If you want safe and sound, use pg_dump/restore.
