I can attest that all of 8.3's performance improvements as well all of
the really useful new functions like the one mentioned here make it
well worth the effort to upgrade. I haven't been as excited
et me guess I have to upgrade.

Noticed that string_to_array does not handle double spaces very well.
If there are double space between the tokens, there is "" (empty string)
in the array returned. Not exactly what I expected.
Try regexp_replace

Within my table there is a field DESCRIPTION that I would like to parse
and split out into other fields.
Within DESCRIPTION there are spaces that separate the data items.
String_to_array(description, ‘ ‘) does the job very well.
I need something like this to work.

Extensive support for a variety of variable types
You can create a running total provided that you have a unique
sequentially increasing (or decreasing) ID for each row. See the
following example:
create table tran(id int primary key, price dec(8,2));
insert into tran values(1,5.00);
insert into tran values(2,4.00);
insert into tran values(3,10
