Re: [GENERAL] need help with query, how to fold select result to array?
but I have to fold it in multi-dimensional, array like {{71629130,
15518, 0}, {2668722, 616, 0}} ?
but it's not possible to pass more then one argument to the array_agg

You can use array_agg(since 8.4):
test=# create table bla (id int, value text);
CREATE TABLE
test=*# copy bla from stdin;
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
1 bla
1 foo
1 bar
2 foobar
2 test
\.
test=*# select id, array_agg(value) from bla group by 1 order by 1;
id | array_agg
+---
1 | {bla,foo,bar}
2 | {foobar,test}
(2 rows)
If you don't have 8.4 search the docu for array_accum:

I want something like that, but without varchararray type;
parentheses, slashes and in array_agg field, where does it get from?

[GENERAL] partitioning question. need current month and archive partitions.
Hi All!
I have a table - transaction pool - with a lot of rows, but I use only
data for the latest month, or current year in my computations.
How can I split data to partitions like that if I can't use CHECK
constraints with non constant objects like, extract('month' from
CURRENT_DATE), extract('year' from CURRENT_DATE):
transaction_pool - master table
transaction_currentmonth - table contains transactions commited
_only_ this (current) month
transaction_currentyear - table contains all transaction for this
year except for transaction_currentmonth rows
transaction_archive - table contains everything except for
transaction_currentmonth, transaction_currentyear rows
Will it be helpful to make such a kind of partitioning?
Thanks a lot!

Re: [GENERAL] postgresql unicode lower/upper problem
I modify pg_createcluster and add locale options exec $initdb, '--locale', 'ru_RU.UTF-8', '--encoding', 'UTF-8', '-D', $datadir then drop and create cluster with my locale. now lower and upper work good with unicode. P.S. it's bad that we can not modify lc_ctype and lc_collate from postgresql.conf like lc_messages, lc_monetary, ... I think that it will be good idea to add locale specific options to pg_createcluster...
