Sorry, I should have said a symlink sits in data/base and points to the
tablespace. My issue is having it point to tablespace/database and not
just tablespace/.

No, sorry for the confusion.

No, I want symlinks in data/base. What I wanted was to have
per-database directories in every tablespace so I can do a 'du' in the
tablespace directory to see how much of each database is the tablespace.
It also nicely partitions the files, makes the directories smaller, and
prevents any possible file name conflict.
