You can control tablespace size by filesystem quotas. When you put each
tablespace on separate FS. Hovewer, disadvantage is that you need admin
access to the machine and it is not controlled by postgres. ZFS works
fine in this case, because you can delegate volume/filesystem
administration to the any user and FS creation is very easy.
