Right, no rename, but I will have to create additional files in 256kb
chunks, and I assume 1gb of chunks remains in pg_clog directory?
Since I have done a vacuum, I assume I just keep creating 256k chunks
until I reach the max xid from the previous release, and delete the
files prior to the 1gb size limit.
