I then tried to put the WAL directory onto a ramdisk. I turned off swapping, created a tmpfs mount point and copied the pg_xlog directory over. Everything looked fine as far as I could tell but Postgres just panic'd with a "file permissions" error. Anybody have thoughts to why tmpfs would not work?

I'd say you got the file or directory ownership or permissions wrong.

I did a mv instead of a cp which duplicates ownership & permissions exactly.
