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
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.

I'm very much learning as I go.

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

I am trying to install postgis 1.5.2 on solaris10. When I run

Is it possible to run maintenance commands like ANALYZE, VACUUM, CLUSTER

The documentations says that those operations can not be done in

during read only mode transactions on the primary [1].

could you check affix file for

also, can you provide link to dictionary files, so we can check if they
