• 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

Spent a few hours dealing with errors on RDS when upgrading from a postgresql 10.6 to 11.1. In case someone else is dealing with the same problems, this might be helpful.

A few things to know about this database:

• PostGIS extension was installed but was not being used
• ip4r extension was installed but was also not used

This probably turned out to be a Good Thing (tm). If you are using PostGIS extensively, I wish you good luck.
