Hello:
Sorry for disturbing.
I am now encountering a serious problem： memory is not enough.
My customer reported that when they run a program they found the totall
memory and disk i/o usage all reached to threshold value(80%).
That program is written by Java.
It is to use JDBC to pull out data

It is to use JDBC to pull out data from DB, while the query joined
some table together, It will return about 3000,000 records.
Then the program will use JDBC again to write the records row by row

Hi there.
I didn't find out why this issue happened. Only backup and format of the
filesystem where corrupted postmaster.pid file existed helped to get rid of
it. Hopefully the file won't appear in the future.

Given a system with 32 cores, an SSD SAN with 48x drives, and 2x 8Gbps
paths from the server to the SAN, what would be a good starting point
to set effective_io_concurrency? I currently have it set to 32, but I
kind of feel like the right setting would be 2 since we have two
paths. We don't

Hi Masao.
Thank you for suggestion. In deed that could occure. Most probably while I

one node and on both nodes DRBD was in primary role. But after the
split-brain occurred I resync DRBD so from two primaries I promoted
Hi to all
On my Postgresql 9.1 instance I had a problem with an index.
Using index I get less tuples than expected.
I try to remove index and the query works fine but obviosly the query is
slow so I try to recreate the index.
I run the create index statement but after a lot of time I get

Hi,
thanks for all your answers.
Ill have a try with the contains operator and the intrange, but before Id like to know if this would work:
CASE WHEN a = 0 AND a 25
CASE WHEN a =25 AND a 50
There wouldnt be a double endpoint. I just have to decide which range the endpoint includes.
