MacOS: remap the built-in keyboard's "§" key (left of the digit row) to ` / ~

	#!/bin/bash
	#
	# Remap the built-in keyboard's "§" key (left of the digit row) to ` / ~
	#
	# The MacBook has an ISO keyboard, so the key left of "1" natively types §/±.
	# We swap HID usages 0x35 (grave) and 0x64 (ISO non-US backslash) so that key
	# types `/~ again, and § moves to the key left of Z.
	#
	# NOTE: /usr/bin/hidutil must be granted Input Monitoring or this silently
	# fails -- see the MANUAL STEP below. Character-key remaps need TCC; modifier

Script to run psql, pg_dump, pg_restore over http proxy

	#!/usr/bin/env bash
	# Run a libpq tool against the DigitalOcean database through the HTTP proxy.
	#
	# Direct connections are throttled by Russian DPI (clean ICMP, but long-lived
	# TLS sessions stall). This wrapper opens a socat tunnel through the HTTP CONNECT
	# proxy in $http_proxy and exports PG* env vars so the wrapped command connects
	# to it automatically. Pass only the tool and its non-connection flags:
	#
	# with-pg-proxy psql
	# with-pg-proxy pg_dump --table=public.sometable > sometable.sql
