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 *.*

Methods of Signing with GPG on MacOS

Last updated June 23, 2022

There are now two ways to approach this:

Using gpg and generating keys
Using Kryptonite by krypt.co

This Gist explains how to do this using gpg in a step-by-step fashion. Kryptonite is actually wickedly easy to use-but you will still need to follow the instructions

	package main

	import (
	"net/http"
	"io/ioutil"
	"time"
	"log"
	"os"
	)

	#!/usr/bin/env ruby
	#
	# Usage: git-up
	# git-reup
	#
	# Like git-pull but show a short and sexy log of changes
	# immediately after merging (git-up) or rebasing (git-reup).
	#
	# Inspired by Kyle Neath's `git up' alias:
	# http://gist.github.com/249223

	#!/bin/sh

	# Called by "git push" after it has checked the remote status,
	# but before anything has been pushed.
	#
	# If this script exits with a non-zero status nothing will be pushed.
	#
	# Steps to install, from the root directory of your repo...
	# 1. Copy the file into your repo at `.git/hooks/pre-push`
	# 2. Set executable permissions, run `chmod +x .git/hooks/pre-push`
