PSQL

Magic words:

psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*

	include MetaTags::ViewHelper

	alternate = []
	params = request.path_parameters
	params[:locale] = I18n.default_locale
