Yes, it sucks, but I have to live with it right now (I've also removed
a lot of code from the function to make it more readable for you)
There are a lot of other parameters and execute commands :-(
Since I don't run >=8.2 I cant use FOR-EXECUTE-UPDATE-RETURNING.
So I will have to find another way.
But if UPDATE sets FOUND, what is the reason for EXECUTE not to set
FOUND if the query executed is an UPDATE?
Is it because it is impossible to tell in advance what kind of query
an EXECUTE statement will acctually execute?
