So, my question is this: My server currently works great, performance wise.
I need to add fail-over capability, but I'm afraid that introducing a
stressful task such as replication will hurt my server's performance. Is
there any foundation to my fears? I don't need to replicate the archived log
data because I can easily restore that in a separate step from the nightly
backup if disaster occurs. Also, my database load is largely selects. My
application works great with PostgreSQL 7.3 and 7.4, but I'm currently using

I'm eager to hear your thoughts and experiences,

Well with replicator you are going to take a pretty big hit initially during the full
sync but then you could use batch replication and only replicate every 2-3 hours.

I am pretty sure Slony has similar capabilities.
