# PostgreSQL Notes

For first time Postgres users, the tutorial section on the documentation is a must read: http://www.postgresql.org/docs/8.4/interactive/tutorial.html

### Installation

Easiest way is to use your package manager (yum, apt-get, etc). On MacOS, macports made it easy. Building the source is straightforward as well. There are plenty of resources online...

### Get acquainted with psql

hgmnz

create table count_cache (
  id serial primary key,
  table_name varchar(255) not null,
  count int not null
)

create table people (
  id serial primary key,
  name varchar(255) not null
)

hgmnz

include 'singleton'
class Configuration
  include Singleton
 
  def self.run
    yield Configuration.instance
    
    post_config_process
  end
end

hgmnz

# which most users need to modify for running PostgreSQL in production, 
# including extensive notes on how to set each of these.  If your configuration
# needs are more specific, then use the standard postgresql.conf, or add 
# additional configuration options to the bottom of this file.
