on delete rules on a view problem

Hi all,

I'am a bit puzzled. I have a view and some delete rules defined on it. Now my problem is, only one gets executed (the
firstone) and the other ones seem not to be executed at all. I use a subselect within those rules (which works fine for
thefirst one by the way) and I wonder if this could be a problem? Are there any caveats? Is it important which of
thesesrules is the do instead rule? 

Are there any things to be considered with using delete rules? I don't find any exhaustive documentation on the
internet(except pg manual), so any pointers will be appreciated. 

Many thanks
Jürgen
