@ray, well, I thought that, too, but apparently this file gets updated from time to time. In the calcentral [README.md](https://github.com/ets-berkeley-edu/calcentral/blob/master/README.md) file, at the bottom, there's this section called "Keeping developer seed data updated" where it says you have to execute this:

<pre>pg_dump calcentral --inserts --clean -f developer-seed-data.sql -t link_categories \
-t link_categories_link_sections -t link_sections -t link_sections_links -t links \
-t links_user_roles -t user_auths -t user_roles -t user_whitelists \
-h postgres-hostname -p postgres-port-number -U calcentral</pre>

If that's the case, then those alter table statements that give ownership to user "calcentral" will surely reappear anytime somebody decides to update the seed data.  

So, that's why I just decided to comment them out at runtime.  They could just as easily be deleted at runtime, but not directly in the file itself because it can't really be trusted.
