removing a user who owns objects

What am I missing?

I want to remove a user who owns databases and objects.

I can change the owner of a database by updating the datdba field in
pg_database.

This allows me to drop the user!

However, the user still owns other objects. So, I have found that I also
need to fix ownership for:
pg_aggregate - aggowner
pg_class - relowner
pg_operator - oprowner
pg_proc - proowner
pg_type - typowner
in each database.

YET, I still have problems as my java program fails with an error:
"pg_aclcheck: invalid user id 111"

Is there something else I am missing?

Thanks for the help,
