I've posted a [plan] to implement [PGAN], a CPAN for PostgreSQL extensions. I've tried to closely follow the [CPAN philosophy] to come up with a plan that requires a minimum-work implementation that builds on the existing PostgreSQL tools and the examples of the [CPAN] and [JSAN]. My hope is that it's full of JFDI! I would be very grateful for feedback and suggestions.
