Hi,

I think I understand what the problem is. This is what should happen:

(1) conn1: insert into database A => sequence 1
(2) conn1: insert into database B => sequence 1
(3) conn2: insert into database A => sequence 2
(4) conn2: insert into database B => sequence 2

And what sometimes happens is:

(1) conn1: insert into database A => sequence 3
(2) conn2: insert into database A => sequence 4
(3) conn2: insert into database B => sequence 3
(4) conn1: insert into database B => sequence 4

That means, connection 1 is "overtaking" connection 2 in this case.
I'm not sure what is the best way to solve this problem; one way of
course is disallow using auto-increment keys, or at least document the
problem. That would be a pity, because sequences are very useful, but
I'm afraid this is what I will have to do.

I didn't test so far if using sequences manually works (first select
the next value from a sequence, and then, in a separate statement, use
that value to insert into the table).

Regards,
Thomas
