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)
    •
