After the first execution of integration tests, i faced with ERROR: schema "ztest_schema1" already exists.

By adding "DROP EXTENSION IF EXISTS hstore CASCADE;" before creating hstore extension, this problem solved for me. (I think because of failure on creating existing hstore extension this error propagates!)
