Your hardware should also be able to run Postgres on BeOS

http://www.bebits.com/app/2752

Being the only non-unix "port" before/besides win32, it could be an
interesting excercise.

You should be able to get and installable BeOS itself from SourceForge

Is this NTFS ?

Any possibility of trying the same tests with SCSI disks ?

I remember having problems with UNIQUE columns having duplicate values a
few versions back on Linux-ext2-IDE. Could this be the same problem or
must it be something completely different ?

BTW, are the tests portable enough to run also on MSSQL, Oracle and DB2
?

I know that you can't publish exact results, but perhaps something like
the GreatBridge results - the one that runs only on Win32 did so-and-so,
the one that has 'i' at the end of version number this, and the one
whose name consists of two letters and a number did that ?
