Epgpb = poolboy + epgsql,
Desc   = "A standalone PostgreSQL database connection pool server 
       	    application, created to support declarative application 
	    composition".

This code is not much more than the poolboy epgsql example with the full epgsql API implementated in poolboy workers. A code generator (see gen/) builds this application dynamically from the compiled epgsql binaries.

To use this with rebar:

  • declare epgpb as a dependency of your application,
  • define your poolboy/epgsql configuration for the epgpb application,
  • run rebar get-deps compile, and
  • run erl and start the epgpb application.

To build and run the example:

The example requires a dummy user and database. To allow the example user to login, you need to modify your pg_hba.conf to include the line:

local   db1     db1     password

To setup the example database and role (both "db1").

cd example
sudo -u postgres ./setup_run_as_user_postgres.sh

It will ask for a password for user db1, type in abc123. From there, it's just:

rebar get-deps compile
./start.sh
application:start(epgpb_example).
