Each of these plugins for Munin generates graphs for all the databases in the PostgreSql instance. So, if you use pg_databases_size.py, the graph will contain the size of every database (including template0 and template1). You may exclude databases (see below).

A simple and INSECURE way to install (based on default locations of Munin on Ubuntu 10.10):

~$ cd ~
~$ git clone git://github.com/hgdeoro/postgresql_munin_plugins.git
~$ ln -s ~/postgresql_munin_plugins/src/hgdeoro/munin/pg_databases_size.py \
            /etc/munin/plugins/pg_databases_size

To setup host, port, username, password, to which db to connect, add the folowing lines to in '/etc/munin/plugin-conf.d/munin-node':

[pg_databases_size]
env.pg_host localhost
env.pg_port 5432
env.pg_db_connect template1
env.pg_user postgres
env.pg_passwd <NO DEFAULT>

The only required parameter is env.pg_passwd

The list of databases to ignore could be specified with 'env.pg_ignore_db', separated by commas:

env.pg_ignore_db db_to_ignore,postgresql,template0,db2,db3
