...Will generate and attempt to execute a bad sql script shortly after execution.  The chief error looks to be a repeated CREATE TABLE [TABLENAME] in each of the CREATE TABLE statements.

Steps to recreate:
-create an external system pointed to a blank postgres database

-start a gsh container and run:
import edu.internet2.middleware.grouper.ddl.GrouperDdlDataMigration;
new GrouperDdlDataMigration().assignDatabaseFrom("grouper").assignDatabaseTo("targetDB").migrateDatabase();

Error should occur shortly after execution starts.
