I removed the not null contraint on members.admin and "update items set active = false where
member_id=38" results in the count columns in members getting updated AND members.admin getting
set to NULL. Really bizarre.
I dropped the trigger function and the trigger, then recreated both, and now they both appear to
function properly. I don't remember seeing anything in the docs stating that this is necessary, so
I guess perhaps it's a bug?
