Yet another question.. thanks to everyone responding to all these so far.. ;)
This one is basically.. given I have a big table already in COPY format,
about 28 million rows, all keys guaranteed to be unique, I'm trying to find
out which of the following will get the import finished the fastest:
Allen,
a) CREATE TABLE with no indexes or keys. Run the COPY (fast, ~30min), then
CREATE INDEX on each column it's needed on, and ALTER TABLE for the pk and
each fk needed.
Did you ANALYZE after the copy?
If there isn't a significant difference between all of them, performance
wise, I
Nope, still 7.3.4 here.. I am very excited about 7.4 though.. almost as

between the two..
I'll keep this in mind for when I update though, thanks.

is there any way to update the stats inside a transaction? what i have is
something like:
select count(*) from foo;
- 0
begin;
copy foo from '/tmp/foo'; -- about 100k rows
-- run some queries on foo which perform horribly because the stats
-- are way off (100k rows v. 0 rows)
commit;
it
begin;
analyze foo;
ERROR: ANALYZE cannot run inside a BEGIN/END block
i am using version 7.2.3.
Time to upgrade. 7.3 / 7.4 allows this to happen.
