Hi,
i have a stored procedure (a function) in which i must generate a date/time
stamp.
for that i use select * from now(); and store the result into a column
table.
is there a easier way to do that ? i tried to store directly now(); result
but without success.
thx.

Can you show us the full SQL statement?
You could also use CURRENT_TIMESTAMP
Hi Ray,
yes for sure. Here it is:
SELECT count(*) INTO existing_email FROM cust_portal.tmp_newsletterreg;
if (existing_email 0) then
{
result = false;
}
else
{
result = true;
INSERT INTO cust_portal.tmp_newsletterreg VALUES

Hi Alain,
That won't work; you just need
... values ( email, session, CURRENT_TIMESTAMP)

So thanks a lot to everybody... so here is the result.
1. the semicolon was missing after the INSERT as wrote Raymond.
2. CURRENT_TIMESTAMP works great
3. i use pl/pgsql as language
thanks again.

The count procedure appears to be working well.
Thanks Adrian for your help.

Hi,
I have an upgrade script that is supposed to install items into a
postgresql database if they don't already exist. One of the items I'm
having a hard time with is aggregates. I want to check if aggregate
foo doesn't exist, then run an SQL command to generate it.

Seems to me you'd rather want the proisagg column in pg_proc and forget
about pg_aggregate

Well, you can use a plpgsql function with a BEGIN/EXCEPTION/END block to
eat the error message. However I'm wondering whether you should be
checking the aggregate argument type(s) as well.

We have pretty big production database (running PostgreSQL 8.3.1) with

least) -- constraint exclusion is able to select correct partitions.
However, there is an exception: queries on partitioned tables using

It is 'ON'. The problem is that it does not work well for 'UPDATE foo
... FROM bar' queries, when partitioned table 'foo' is joined with
another table.

Tom,
Thanks for the patch. We've tried it here, and it improved query plan
slightly (indeed, it looks exactly like the plan from 8.2.6 now).
But, as you've said, empty sub-joins are still not discarded, so query
execution time did not improve. And this is the same in both 8.2 and 8.3.

Tom,
If you're feeling brave, try the patch I just committed to CVS.
I just did it. It works! According to the query plan, only one partition
is being examined now.
Is this patch going to be included in 8.3 only, or in 8.2 as well?
Thanks!

I thought I was already taking a chance by putting it in REL8_3_STABLE.
Since 8.2 doesn't have a regression compared to the previous release,
and is also very much more different from HEAD,
