Hello,
I have a few questions about streaming replication.
We have a database of nearly 300 GB.
We are using Postgres 8.3.1 and Slony for replication on Ubuntu 10.04.
We have 4 Postgres servers PGMaster1, PGSlave1, PGMaster2 and PGSlave2 on 2
distant sites (distance between the 2 sites is nearly
Hi! I have a big table with about 26 millon registers, and I have 3
partitions, one that handles daily information, only one register per
day for about 24,000 elements, that's it about 24,000 register daily,
other one that handles one register per minute per day, only 8 hours a
day, for about 9000
Question 1 : is it possible to have such a replication configuration
with the streaming replication of PG9 (cascaded replication) ?
Nope, as far as I have tested pg only has 1 master and can have
a number of slaves, so having 2 masters is not possible.
Question 2 : All the proce

I'm very much learning as I go.
I've followed your example from top to bottom - your sample code works -
however its not clear to me how to execute the generate_crosstab_sql
function to produce the results in one single step.
I've tried this:

How do you create an index for only some of the rows in a table? I

Hi All -
I am trying to install postgis 1.5.2 on solaris10. When I run
the configure I get the following.

is there some setting I need to do to make it work?
$./configure --prefix=/opt/postgr
It's just a warning, continue happily onwards. Just means a few unit tests
won't be run.

Hi,
Is it possible to run maintenance commands like ANALYZE, VACUUM, CLUSTER
on a standby server ?
The documentations says that those operations can not be done in
recovery mode, but that "some of these commands are actually allowed
during "read only" mode transactions on the primary" [1].

Jens,
could you check affix file for
compoundwords controlled z
also, can you provide link to dictionary files, so we can check if they
supported, since we have only rudiment support of hunspell.
btw,it'd be nice to have output from ts_debug() to make sure dictionaries

thanks for your answer.
First I checked the links in the tsearch_data directory

Then I recreated them by using pg_updatedicts.
This is an extract of the de_de.affix file:
