Connect to a postgres instance, run a query, and disconnect.

Typically you will access the PostgreSQL server through a pool of clients. node-postgres ships with a built in pool to help get you up and running quickly.
var pg = require'pg';var conString = "postgres://postgres:1234@localhost/postgres";pgconnectconStringiferrreturn console.error'error fetching client from pool' err;clientquery'SELECT $1::int AS numbor' '1'//call `done()` to release the client back to the pooldone;iferrreturn console.error'error running query' err;console.logresultrows0numbor;//output: 1;;
Documentation is a work in progress primarily taking place on the github WIKI
To use native libpq bindings replace
The two share the same interface so no other code changes should be required. If you find yourself having to change code other than the require statement when switching from

You are welcome contribute via pull requests. If you need help getting the tests running locally feel free to email me or gchat me.
I will happily accept your pull request if it:
Information about the testing processes is in the wiki.
If you need help or have questions about constructing a pull request I'll be glad to help out as well.
If at all possible when you open an issue please provide
Usually I'll pop the code into the repo as a test. Hopefully the test fails. Then I make the test pass. Then everyone's happy!
If you need help or run into any issues getting node-postgres to work on your system please report a bug or contact me directly. I am usually available via google-talk at my github account public email address.
I usually tweet about any important status updates or changes to node-postgres.
Follow me @briancarlson to keep up to date.
node-postgres is by design low level with the bare minimum of abstraction. These might help out:
If you use node-postgres in production and would like your site listed here, fork & add it.
