I'm happy to announce that my db_console plugin for Rails has just been added to Rails Core.

Ever tried using 'psql' or 'mysql' on the command-line to connect to your Rails database, only to find you forgot how to specify all those '-u' and '-h' parameters?

This plugin provides handy rake tasks for running DB console programs for the various databases in your database.yml. It supports postgresql, mysql, sqlite and sqlite3 connections.
