Hello List,
I want to write a statement-level trigger - one that happens once per
statement - such that, immediately after an insert into a table(which
gets a unique integer value as an ID from a defined sequence, being the
primary key on the table), a new table is created with foreign key
the correct one.
Does that sound plausible?
Thanks,

Hello all,
Is there an existing mechanism is postgresql that can automatically
increment/decrement on a daily basis w/out user interaction? The use
case I'm considering is where a student is in some type of contract with
an instructor of some sort, and that contract puts a time limit on the
that are standard
in the industry or are we stuck with this type of external influence?
Thanks all!

Rhys,
You could create a sequence, then make the seq attribute to your table
have a default value of:
seq integer default nextval('your_sequence')
Then every time an insert is done into your table, the seq will
increment. You alternatively could make your insert statement have

Hello List,
PostgreSQL 8.0.1 (on Solaris 9)
There is a PERL program that a friend purchased which is used to create
tables on a MySQL database, and of course ;) I want to run this on a
PostgreSQL database server instead. The below is the code:

As you are working on transferring, maybe you like to drop those

What about creating views on areas of the table that are queried often?
I don't know if you have access or the ability to find what type of
trends the table has, in terms of queries, but if you create some views
on frequently visited information, this could also help.

Are you certain:
You can only create an FK if the fields you are referencing in the
foreign table form a PK there. And creating a PK implicitly creates an
index, which you can't drop without dropping the PK :-(
I'm not sure I am convinced the necessity of a foreign key,
, always have a 1-1 Index per row entry. At least that's the way I
understand it, can someone else affirm this statement or redirect a
misguided 'me ;)'?
Thanks group,

Try using the following format in the pg_hba.conf file:
host all all(or your_user_account) your_IP/32 trust (The 32 is the same
as 255.255.255.255 but in CIDR format)
As for the command line you started postmaster with, doesn't the -i
require an interface such as an IP address too? If you
your_PORT -l logfile(if you wish) start
if you use your_IP = 0.0.0.0 it will listen on all valid TCP/IP
interfaces, including 127.0.0.1(a.k.a. localhost)

PHP is one alternative, another is PERL with CGI to write web based
programs that can GET/POST with input/output from the browser, and to
interface with *SQL - i.e. postgresql - you can use PERL's DBI interface

What is the current schema layout for your db instances? I don't think
it's possible to share across db instances like this:

But you can share resources of the following type:
