Short Description
Bugs Inserts Arrays

Long Description
Hi, Im Walter, from Brazil, and I use PG 7.2.
(excuse my english!)
The error: the last entrance (last array
dimension) determine the dimension of all arrays,
losting data information.

see the example:
all of array has 2 elements. The error: the last entrance (last array
dimension) determine the dimension of all arrays,
losting data information (the information "002" of first array is lost).

If I make a mistake, forgot it, but if not, please, report me something !

Thanks a Lot

Walter



Sample Code
create table teste(serie integer,aula text[][]);
//it�s ok when insert this
insert into teste values (1,'{{"004","009"},{"009"},{""},
{"001","002"}}');
//But when I insert this..
insert into teste values
(1,'{{"004","009","002"},{"009","001"},{""},{"001","002"}}');
                  ^^^^^^ -> lost information  ^^^^^^^^^^ -> array dimension last entrance.

Yeah, this seems to be a long-standing misbehavior.  I get the same
results as far back as PG 7.0 (the oldest version I have running):

play=> select * from teste;
 serie |                        aula
-------+-----------------------------------------------------
     1 | {{"004","009"},{"009",""},{"",""},{"001","002"}}
     1 | {{"004","009"},{"009","001"},{"",""},{"001","002"}}
(2 rows)


On the other hand, the last time I fixed what seemed an obvious bug in
the array-value parser, I got flak for it.  Anyone want to defend the
present behavior?
