Re: Partitioning...

Thanks for the prompt reply Tom,
What is wrong with random() ?

The following snipped is working ...

insert into part(id1, id2, filler)
select
11 + round( (random()*9)::bigint,0) as id1, --- 11-20 range for id1 , as of definition
round( (random()*20)::bigint,0) as id2,
'TTTTTTTTTTTESTTTTTZZZZZZZZZZZZZZZZZZZ'
from generate_series(0,100000);

Regards. Milen

Don't use random() in your test case.
