The fresh-initdb approach is more likely to work without any strange corner cases. If you try a setup where the system catalogs are on persistent storage but you have a tablespace on ramdisk, then after restart you'll have pg_class entries referencing files that don't exist anymore, which I believe will provoke errors. Also, I doubt the OP wants his WAL on real storage either ... regards, tom lane
