Given those parameters, you should expect a "slack" proportion of about
1/6th
Thank you Michael, your suggestion works a charm (though I didn't

Hi there everyone,
I'm having trouble getting the data I want from my tables.
Here is a simplified version of my tables:

create table lefty (
day date,
good numeric(10,2),
grp integer
);
insert into lefty values ('2005-06-01',5.00,1);

Hi,
I messed around with the following problem and just want to let you know.
I have the following function:
-CREATE OR REPLACE FUNCTION
usp_inventaire_transaction_inserer("varchar", "varchar", int2,
"varchar", "varchar", "varchar", int4, "timestamp", "timestamp",
"numeric", "numeric"
There are probability* *a few around, but i think most people just use a
flowcharting software to created designs. I know for the work that i do
with postgresql i use smartdraw as it can do anything i want then i
apply these designs to postgresql using EMS Manager.

In a trigger function, I'm trying to refer to a column given by an argument
to the trigger function.
The trigger function fires on deletes and is responsible for deleting messages
that are referred to using foreign keys which are named differently in different
tables (thus the foreign key's column

Many thanks Karsten. I got a system working with arrays yesterday but
will still be examining your code. I guess the next challenge is to see
how well the multidimensional array can be searched. I guess I could
make indexes on an expression to retrieve language for a specific key

I imagine because the name of the program as seen by the kernel (for
example with ps) uses the name the program was started with, not the
name of the actual binary. That way you can use the same binary for
multiple purposes.
