Redundancy software for PostgreSQL

Carlos wrote:

Hello Forum,

I would appreciate it if you could recommend software to build
redundancy in my application (my application stores data in a PostgreSQL
v7.3.x database running in Linux RedHat) The software would replicate
or copy the database from a main server into a second server. And when
the main server goes down, the redundant database could still be
available in a view mode -- where most tables cannot be updated and only
a couple of tables can be modified. In this way, when the main server
goes down, the users could still view data and when the main server goes
back on-line, I can update a couple of tables of the main database with
the data from the redundant database.

Thanks in advance for your response.

Hi,

Take a look at this:

PS: I don't use it so I can't tell you more, sorry.

Why not doing a full failover?
