Title: Address the dump file format for hstore

When ActiveRecord unit tests are tested with PostgreSQL v9.1.2(hstore installed),
Always got a failure as follows.

```ruby
$ ARCONN=postgresql ruby -Itest test/cases/schema_dumper_test.rb -n 'test_schema_dump_includes_hstores_shorthand_definition'
Using postgresql
Run options: -n test_schema_dump_includes_hstores_shorthand_definition --seed 31050

# Running tests:

F

Finished tests in 1.178730s, 0.8484 tests/s, 1.6967 assertions/s.

1) Failure:
test_schema_dump_includes_hstores_shorthand_definition(SchemaDumperTest) [test/cases/schema_dumper_test.rb:242]:
Expected /t.hstore "hash_store", default => ""/ to match "# ... snip ...
```
The dump file output is slightly different from current test code.
