waiting for pg 8.4
i will try to follow development of 8.4, and write examples of what's possible with it, based on current HEAD code.
of course there is no guarantee that it will work in final, released 8.4 (it is a bit too early to talk about it, but given the fact that the patch got committed, there is pretty good chance we will see it whenever 8.4 will be released.
today 2 new features: limit (select ) and optional as in select.

also, i hope to extend it in future if/when i'll find something else that can be added/changed in proposed solution.
so, without further ado, let's start:

avoiding “empty” updates – part2
how to check if given update is from trigger or why i hate orms?
- we use orm
- yes, and?
- and we have a problem with it…
- you already said that
now, imagine a simple scenario:
- objects table (let's name it “topics"), which contains column: posts_count
- sub-objects table (posts), with foreign key to topics
- triggers which update posts_count on insert/update/delete on posts
simple? yes? well. it was. now, enter disaster: orm.

how many 1sts of any month were sundays – since 1901-01-01?
nixternal wrote about boost library for c++.
with it he was able to find the answer to title question in miliseconds (he didn't specify how many, but let's assume that is was less than 10 ms).
