Subject: multiple standby configuration
Date: Tue, 31 Aug 2010 11:36:31 +0200
Message-ID: <4C7CCD1F.6010503@tech.sdb.it> (raw)

Is it possible to have multiple host destinations in the archive_command 
parameter of postgresql.conf to be able to mantain 2 standby datbase 
with write ahead log???

Can we use something like:

archive_command = '/usr/bin/scp -Cv "%p" 
host_standby1:/var/lib/pgsql/archivelog/"%f" && /usr/bin/scp -Cv "%p" 
host_standby2:/var/lib/pgsql/archivelog/"%f" '


But in this case if the first scp fail, will skip the second scp command ???

Morevoer,

is it possible to architect a cascading standby ,  that means a  
secondary standby  with the archivelog shipped by the first standby
 primary-> standby1->standby2

Thanks a lot

Silvio B.
