Hi,
we are contemplating the possibilities for a Postgres HA installation.
As the rollout is targeted towards the end of the year, 9.0 and it's new

Now from a HA point of view, what is the major difference between 9.0's Hot
Standby and 8.x's Warm Standby?

Taking SQL backups without impacting the master might be something to consider.
Interesting point. Thanks for mentioning that.
Greg Smith, 10.07.2010 14:44:
Is there a difference in how much data could potentially be lost in
case of a failover? E.g. because 9.0 replicates the changes quicker than 8.4?
There's nothing that 9.0 does that you can' t do with 8.4 and the right
software to aggressively ship partial files

Yes, but if you try you'll discover that actually getting any shared
disk or file system replication solution setup so that you really do
achieve less failover loss than the file shipping approach will be
expensive, complicated, fragile in its own way, and just

The problem with a batch file is that you will need to provide the password

But if that isn't a problem (and you actually know the superuser password of

Not sure what you mean by community edition. There's PostgreSQL.
From the postgresql.org website, which is what most folks use.
I think the term community edition was coined by EnterpriseDB - at least it
shows up on their webpages on some places.
