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. I have seen similar reports in the past. In tht case the problem was that after rows were removed from one table, the corresponding rows from the other table could not be found because they were selected using a join and the rows they were supposed to match up with were gone now.
