londiste and I believe Slony require a superuser connection in order to
manipulate some settings. Actually, Slony requires shell level access
because its logging trigger is in C, so unless the extension is already
available I don't see Slony working. I know that you get an account
similar to superuser on RDS, so it's possible that it'd work.
That said, can't you use binary replication to an EC2 instance in west-2
and then cascade that replication to an EC2 instance in East? AFAIK
that's supported. I think you can replicate into RDS as well.
