Issues with ubuntu 14.x

For some reason the commando bucardo install tell me that the language
plperlu is not installed, but ubuntu say is already install.

INSTALLATION FAILED! (psql:/usr/share/bucardo/bucardo.schema:46:
ERROR:  language "plperlu" does not exist
HINT:  Use CREATE LANGUAGE to load the language into the database.)

apt-get install postgresql-plperl-9.3

>> Yup, if you need a writeable database cluster you need to use a logical replication system like Bucardo.
>> The main difference between the master-master examples and normal master-slave would be that when defining the sync instead of having `bucardo add sync foo dbs=source:dbA,source:dbB,source:dbC` you just need to provide the list of the individual databases.  Bucardo assumes (unless otherwise told) that the databases are given in the order of source, target, target, […].
