We have been using XFS for about 6 months now and it has even tolerated a controller card crash. So far we have mostly good things to report about XFS. I benchmarked raw throughputs at various stripe sizes, and XFS came out on top for us against reiser and ext3. I also used it because of it's supposed good support for large files, which was verified somewhat by the benchmarks.
I have noticed a problem though - if you have 800000 files in a directory, it seems that XFS chokes on simple operations like 'ls' or 'chmod -R ...' where ext3 doesn't, don't know about reiser, I went straight back to default after that problem (that partition is not on a DB server though).

i have only a little question. Which filesystem is preferred for
postgresql? I'm plan to use xfs (before i used reiserfs). The reason
is the xfs_freeze Tool to make filesystem-snapshots.
Is the performance better than reiserfs, is it reliable?
best regards,
Martin
