are you getting to the point of migrating large XFS filesystems to ext4 for production databases yet? Or at least using ext4 in new large-scale filesystems for PG?
Not really. Last time I checked (a few months ago), there were still some scary looking bugs in ext4 that concerned me, and I've seen one difficult to explain bit of corruption on it. Lots of these bugs had been fixed in the mainline Linux kernel, but I wasn't sure they'd all been backported to the sort of distributions my customers run. I expect to re-evaluate RHEL6 to see how it's doing soon, just haven't had time/requests for it.
