PostgreSQL command line cheatsheet

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

  • -E: will describe the underlaying queries of the \ commands (cool for learning!)
  • -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

OpenWrt: Allow only CloudFlare to access HTTP 80 and HTTPS 443 ports. Use if your uhttpd is hidden behind CF. Put this file to /etc/firewall.user. NOTE: It uses HTTP to get the list of IPs because to wget via https we need to install ca-certs. This makes you vulnerable to MiTM attacks but that's ok to be protected from internet's hackers
