Re-run PostgresSQL Script

[Melody]

For some reason, the installation script stops in the middle without exception. As a result, we find database objects are missing, such as generateticketactivity(), or null columns are not updated. This doesn't happen often, but it'd be great if we could have the re-install functionality.
Can you please modify the script to allow re-run ? We need to get the biggest table dms_sample.sporting_event_ticket dropped in the re-run as a higher priority, otherwise, it will keep growing and fill up the DB disk space quickly. Thanks.

Here are errors in the table drop at the moment:
