Your original post had:

FATAL: *"pg_tblspc/113608/PG. 9.3_ 201306121/18364" is not a valid data
directory

PG. 9.3_ 201306121/18364 does not look like PG_9.3_201306121\18364.
To me it looks like a case of corrupted symlink(or whatever it is called
on Windows).

You were right. I was able to correct them and restart the database.
