Jade,
I don't quite get what you mean. The query I wrote works very well in psql, so I guess that either the __delete function gets always the id in my query (it should, at least), or it works even with cursor.
Either way, the problem is rather that it returns a value for every row that matches so it breaks 0or1row, like Don says.
I solved this by moving all this code to the package api of users-selection, where it imho should have been in the first place. That way, us_selection__delete takes care of cleaning up stuff that is related to it, and every developer calling for that proc doesn't have to delete the comments explicitly.
I thought about something like Don's wrapper trick, but came to a conclusion that moving the code is actually not that big a task and it should make the overall code cleaner.
Thanks for the feedback!
