PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

  • -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)
