Check for CREATE privilege on the schema in CREATE STATISTICS. This omission allowed table owners to create statistics in any schema, potentially leading to unexpected naming conflicts. For ALTER TABLE commands that require re-creating statistics objects, skip this check in case the user has since lost CREATE on the schema. The addition of a second parameter to CreateStatistics() breaks ABI compatibility, but we are unaware of any impacted third-party code.
