cannot load such file -- pg when creating a database

[c-castillo]

Hi,

I'm using the postgresql_database LWRP, and when creating a database, I got an error:

==> my_web: LoadError
==> my_web:
==> my_web: ---------
==> my_web: cannot load such file -- pg

Here is my recipe:

include_recipe "postgresql::libpq"
include_recipe "postgresql::server"

db_config =  data_bag_item('database', 'myweb')

 postgresql_database db_config["database_production"] do
   owner db_config["username_production"]
   encoding 'utf8'
   template 'template0'
 end
