Then, I got the following error when I tried to recreate the database:

I uninstalled the package from the package manager, then reinstalled it but still got the same errors. I'm not sure what went wrong, maybe a typo? (Again, argh). Since I don't have any data yet, is there any way to purge it altogether and clean out any problematic catalog entries? I'd even be content if I could purge everything under $OPENACS_SERVICE_NAME and resinstall openACS without having to start at the very beginning (Postgres) again.

Sorry for all the beginner's posts... Hopefully will get going on the learning curve...

Unfortunately, after double checking the create call file, I pasted over it to try again, so I can't be absolutely sure at this point.

If I assume that I did make a type in the type name, is there anyway to undo the mess?

I chatted with Dave briefly about it. He mentioned it could have something to do with a change in the way views work so that they are not getting dropped?

code should be:
permission::require_permission \
-object_id $package_id \
-privilege admin

Sorry for the long posting ;). Comments are appreciated, I am not sure this is correct but as far as I checked all the references to mfp_notes are gone now.
