Yup. Plus it seems rather silly to expect every port/package of
PostgreSQL to add code to check for functional tablespace mounts.

Perhaps an easy means would be to put a PG_VERSION file in each
tablespace when it's created and then check all of them. Tablespaces
arguably make it slightly easier to accidentally try and mount something
from a different version...
