pg-promise 6.x
Promises/A+ interface for PostgreSQL.
This is 6.x branch of pg-promise, temporarily distributed as a pgp package:
$ npm install pgp
...until the day when it is ready to become the master branch that is.
The only difference from the master branch is that it uses the latest version of node-postgres,
automatically creating and maintaining a separate pool for each database.
