Subj:   Re: RDBMS Error 2802: Duplicate row error
From:   Victor Sokovin

  There is a small typo in the query. It should look like -  

     >UPDATE T1 FROM table01 T1, table02 T2
     > x1 = T2.x1
     >WHERE T1.pk1 = T2.pk1

Isn't the problem caused by the fact that T2.x1 can be an array for some pk1. All the values would be the same but it is still an array.

To eliminate the array problem you might want to try something like

     update T1
     from (select T1.pk1, T2.x1 from T1, T2 where T1.pk1 = T2.pk1 group by 1,2)
     set x1 = D1.x1
     where T1.pk1 = D1.pk1 ;

I just typed this query and did not test it so some corrections might be necessary.
