In this recipe, we are going to show you the replication between two databases using Bucardo.
This exercise is carried out on a Red Hat Linux machine.
EPEL package for your Red Hat platform from https://fedoraproject.org/wiki/EPEL.
Then, install these RPMs with the following
yum install perl-DBI perl-DBD-Pg perl-DBIx-Safe
If it is not already installed, download the PostgreSQL repository from http://yum.pgrpms.org/repopackages.php.
After this, install the following package; this is required because Bucardo is written in Perl:
yum install postgresql93-plperl
