Are you sure the pg data directory is on the drive you think it is? Are
you doing alot of deletes or are you merely inserting? Are you doing
any sorting and therefore running

Which makes me wonder, does copy accept UTF-8 input? Is it possibile
to use some unicode character which is unlikely to appear in the data

I'm also not able to get unicode characters to copy in

Of course it is, but really latency probably isn't the key issue - more

My problem is, I need to benchmark set of tables, where - we can
assume - schema of each table is unknown, and we have no assumption on
any fields being present there. (altho, if there is no other way to do
it, we could assume id bigint not null default nextval('someseq'));

Regular SERIAL type is limited to a 32 bit int. BIGSERIAL uses a 64

I think one of the things that would be offsetting is the size
difference between the two types (32 vs 64 bits, 5 foreign keys, and a
billion rows or so makes

Another question, how many people are there maintaining this huge database.
We have about 2T of compressed SAS datasets, and now considering load them

according to your experience, it seems a single PostgreSQL instance
Just out of curiosity, how do you replicate that amount of data?
When I started working here, we used Slony-I to replicate our aggregate
fact tables. A little over a year ago our data volume had grown to the
point that the Slony was regularly unable to keep up with the data
volume and around
If you put this in the application, you could do something such as:
my @manufacturers = fetch(select manufacturer_no, name from
manufacturers);
my @select_fields = ('product_no');
foreach my $manufacturer (@manufacturers) {
my $manuf_no = $manufacturer-{manufacturer_no};
my $name =

In real use you're unlikely to hit any limits, theoretical or
practical, but if you start to use a silly number of tables and so
on
you're likely to hit
update foo
set foo_id = g.goo_id
from goo g
where foo.foo_id = g.goo_id and foo.foo_id is not null
I think. :)
