What does "it didn't work" in this case exactly mean?

Did some testing with postgres, results;

create table test (arr text[]);
insert into test values ('{"1","2","3","4","5"}');
select * from test;
          arr
-----------------------
 {"1","2","3","4","5"}
(1 row)
update test set arr[4]='8', arr[2]='9';
select * from test;
          arr
-----------------------
 {"1","9","3","8","5"}
(1 row)

So, updating arrays definitely works. Are you having a syntax error
somewhere or what?
