I guess the problem is that you already moved a lot of tables around.

Could you connect to the database and try the following:

SELECT d.datname, d.oid, sp.spcname, sp.oid
FROM pg_tablespace sp JOIN
pg_database d ON sp.oid = d.dattablespace
WHERE datname = current_database();

and

SELECT t.relname, t.reltablespace, sp.spcname
FROM pg_class t LEFT JOIN
pg_tablespace sp ON sp.oid = t.reltablespace;
