How to add more than one database for replication?

[dinesh ddabhi]

I don't want to make another Configuration file. It will create another process to maintain.
config.left = {

:adapter  => 'postgresql', # or 'mysql'

:database => 'database1','database2'

:username => 'scott',

:password => 'tiger',

:host     => '172.16.1.1'

}

 

config.right = {

:adapter  => 'postgresql',

:database => 'database1','database2'

:username => 'scott',

:password => 'tiger',

:host     => '172.16.1.2'

}
It is not possible !!! Is there any other way to do this thing without making another process.
