While em-pg-client is a nice solution to the problem of accessing a PostgreSQL database from within EventMachine, it is somewhat... spartan. ORMs have spoiled us somewhat, and so the appeal of hand-writing SQL and dealing with the finer details of error handling has faded. Hence the creation of the EM::PG::Client::Helper module. It contains a collection of useful helper methods that make it somewhat easier to perform common operations against PgSQL databases.

It's a gem:

gem install em-pg-client-helper

If you're the sturdy type that likes to run from git:

rake build; gem install pkg/em-pg-client-helper-<whatever>.gem

Or, if you've eschewed the convenience of Rubygems, then you presumably know what to do already.

To use any of these methods, you will want to add the following require:

require 'em-pg-client-helper'

Then add this line in any classes you wish to use the helper methods in:

include PG::EM::Client::Helper

The module documentation for EM::PG::Client::Helper has more information on the available methods and how to use them.
