category_id,amount,co_name,city from eyp_listing
where keywordidx ## 'vegetable' and category_id=781 ;
category_id | amount | co_na

To those who pointed at the SELECT currval , thanks!, I think
this is what I need instead of a trigger. So the real problem is solved I
think. However I am quite curious about the plpgsql thing, I think I may
need to use it, or may WANT to use it (performance wise... better to be as
close as po

Does anybody could tell me how to drop a constraint on a column where no name was
provided to the constraint?
How does Pg name constraints?

No need to apologise. Novice would have been appropriate, but SQL is
OK too.

So can you run the executable directly?

Pay attention to the exact message and do not flounder around
aimlessly. There is no
Everything in the path is executable for others.
That is true for:
/usr/lib/postgresql/bin
and for:
/usr/bin

No I cannot use SET TIME ZONE.
SET TIME ZONE will be set by any client backend. But what I want to get
is that DATE_TRUNC('month', ) = DATE_TRUNC('month',
).

Hi
I do not know if it's an error, but in this query
=# select date_trunc ('month', now ());
date_trunc
2002-11-01 00:00:00+01
(1 row)
I've got the truncated date dependant to my timezone.
Instead, I would like to have as a result
2002-11-01 01:00:00+01
which
When I do an 'INSERT INTO VALUES '
and on the table is a serial primary key named p_key.
As I want this number to be auto-generated, but use it as a 'customer
number', I want to create this function to return the value of this
insert.
Try this:
SELECT currval();
