So what you're imagining is

* iterate through each symlink in $PGDATA/pg_tblspc
* check that PG_VERSION exists (and has the right contents??) in
each pointed-to directory
* fail if not

I guess this is reasonable, since we make a similar check for the core
data directory itself. Watch out for the initdb sequence though.
