Either way will work. The advantage to having one on each is that
connections are simpler to configure and if one goes fown you still
have pgbouncer running

hmm ok..

So basically would be:

1 - Install the pgbouncer into the www server
2 - Do the tests to see if it works
3 - Change the APP connection parameters to start using pgbouncer (probably just the port)

Basically would be that, right?

Would my slave01 still be able to work as read-only?
