I'd like to know how to check whether a specific object is created under
a specific *tablespace*? How to find all objects under a specific
tablespace?

See pg_tablespace and pg_class.reltablespace in the "System Catalogs"
chapter of the documentation:

http://www.postgresql.org/docs/8.0/static/catalog-pg-tablespace.html
http://www.postgresql.org/docs/8.0/static/catalog-pg-class.html

For example, one index named "idx_test1" has been created. Now I'd like
to check which tablespace does this index belong to?

Aside from querying the system catalogs, you could use "\d idx_test1"
in psql -- that should show the index's tablespace.
