That's the way postgresql works. Either all statements in a
transaction succeed, or none of them do. Postgres doesn't do the
half-half thing you're looking for.
There are a number of ways to deal with it: first check if the row
exists, use a stored procedure to make the checking transparent. You
can use savepoints to acheive your goal also.
The archives may describe other solutions.
Have a nice day,
