Hi,
I have a query with 20 relations, the GEQO is used to solve this query.
When the value of
pool-data[i].worth
was displayed, from random_init_pool() [geqo_pool.c], exactly the same value
was obtained for all individuals.
Also when the value of pool-data[i].worth was printed from

Hello,
Is it possible to use an implicit sequence with a start value?
Something like: CREATE TABLE foo (key SERIAL START 1000 PRIMARY KEY NOT NULL);
Thank you in advance, Clemens

Well, you can't do it just that way, but you could issue a setval() or
ALTER SEQUENCE command after
Hi Tom,
regression=# alter sequence foo_bar_seq start with 1000;
ALTER SEQUENCE
Completly forgot about that possibility, thanks a lot :)
What still puzzles me is how to get the sequence value applied.
MySQL's auto_increment simply ignores whatever value is supplied to
it, however postgres

Greetings,
I am interested in using the PostgreSQL on machines with Renesas

and noted from this URL (

Hmm, what is the point of introducing extra blank lines into the asm
output? I would hope those are unnecessary, but one never knows
Suppose I've
create table m1 (
a int primary key,
cm1 int,
cm2 int,
...
);
create r1 (
a int references m1 (a),
cr1 int,
cr2 int,

);
and cm1 possible values depends on some function of cr1 for a given
a.
I actually have a plpgsql function that returns the possible choices
for cm1
Is there a transitive closure (or equivalent) operator in Postgres (or
extension)?
Anything like CONNECT BY?
Or any recommended way of querying hiearchial data?
I'm working on improving my background database theory, to aid in practice.
I've found learning relational algebra to be very helpful. One thing which
relational algebra doesn't cover is aggregate functions. Can anyone
recommend any papers or web pages which provide some good theoretical

Yes, recursive common table expression (since 8.4)

The problem is that I don't have control over the SQL generated, that
happens behind the scenes of the JDBCRowSet/SwingSet toolkt/api.
Fourtunatly it seems to work when I simply don't bind the textfield :)

You will need to create a type to represent the record contained in
the array, or use a table type

I'm currently running Postgres 8.2 on Windows XP. I would like to use some
8.4 features, but I don't want to migrate my 8.2. Is there any way to run
both instances together? Are there any problems with that?
Alternatively, is the procedure to move from 8.2 to 8.4 without data or
function loss
