Hi all,
pg 8.2.4 on Fedora Core 6 x86-64, mostly default postgres.conf just
shared memory buffers increased to 256M. 1GB RAM.
I attempt to insert ~200k rows into table in one transaction from psql
console, calling stored function of plperlu language, which inserts row
by row via
Hi all,
I participate on realization of warm standby pg 8.2.3, according to
documentation. Mostly all works fine, but one problem remains. The
recovering rdbms eats transfered wal logs fluently, but I cannot see the
way how to recognize if the recovered wal log file is really processed
into
Hi,
my colleague unfortunately ran some database dump in template1 on our
production server, pg7.3.5. Can we drop template1, dump template0 and
rebuild template1 from this dump? Or does exist some better way how to
repair template1 without any affect of living database instances?
Thanks,
And what about another data representation like
create table r1 (
i int,
chance_from numeric,
chance_to numeric
)
, you can select one random row in one select, for instance
select * from r1 where chance_from = $rnd and chance_to $rnd;
I see these advantages
- Only one select.
- Indices can
Or
create table r1 (
i int,
chance_from numeric
)
and
select * from r1 where chance_from = $rnd order by chance_from desc
limit 1;
which can be easier updated...
Just ideas, I has never tested it...

I have some experience with following scenario:
1. Pg or other RDBMS realizes data integrity and transaction isolation,
only. Potentially, only _very_ well known and oldschool rules are
implemented here, for instance user sessions, which are not strictly
related with real bussiness rules.
Hi,
try this on psql console:
explain analyze select tq1.*, tq2.* from
cal_quat_1 tq1, cal_quat_2 tq2
where tq1.timestamp = tq2.timestamp
and tq1.timestamp '2004-01-12 09:47:56. +0'::timestamp with time zone
and tq1.timestamp '2004-01-12 09:50:44.7187 +0'::timestamp with time zone

Hallo,
we runs PostgreSQL 7.3.4 on RedHat 9. I initialized dbcluster with
--locale=cs_CZ.UTF-8 and created database with --encoding=unicode. But
following script generates error:
-- -*- coding: iso-8859-2 -*-
set client_encoding to LATIN2;
create table t (txt text);
begin;
--inserted character
RedHat 9, PostgreSQL 7.3.4.
When I perform
initdb --locale=cs_CZ
createdb --encoding=latin2 lat
createdb --encoding=unicode uni
, the tables of lat are sorted fine, but the tables of uni not. When I
initdb --locale=cs_CZ.UTF-8, sorts of uni are good, but sorts of lat
not. Is some way to create
Did you think about cluster on index ?
