Can you send me the test data (off-list)?

TIP 4: Don't 'kill -9' the postmaster
I think I have a test case for 7.4.2
So I have a 3 millions of rows table "metadata" with a tsearch2 index.
I had memory leak in "vacuum full verbose analyze"
I drop the index, run "vacuum full verbose analyze", recreate the index
and re-run "vacuum full verbose analyze".
The I run my script to i
Does the order of columns in the index matter since
more than 50% customer_id = 158?
I think it does not in Oracle.
Will the performance be better if I change index
xxx_idx to ("domain", customer_id, created)?
I will test myself when possible.
Thanks,

Merry Xmas!
I have a query. It sometimes runs OK and sometimes
horrible. Here is result from explain analyze:
explain analyze
SELECT module, sum(c1) + sum(c2) + sum(c3) + sum(c4)
+ sum(c5) AS "count"
FROM xxx
WHERE created >= ('now'::timestamptz - '1

Hi,
A small test with 8rc2 and BLCKSZ of 8k and 32k.
It seems there is a 10% increase in the number of transactions by
second.
Does someone plan to carefully test the impact of BLCKSZ ?
