• Download and install VirtualBox.
• Download the CoreOS ISO
• Create a new VM in VirtualBox
  • For the OS, Other Linux, 64-bit should be fine
  • Give the VM 1gb of memory, like your physical hardware has.
  • Create a disk of whatever size you want. I made a VMDK file that could expand dynamically up to 8gb.
• Mount the ISO in the VM
  • Right click on the VM and click settings
• Go to the storage tab

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)
