How to upgrade a Heroku PostgreSQL database to a new plan

How to upgrade a Heroku PostgreSQL database to a new plan

I started a project on a Hobby Dev plan (free, limit 10,000 rows), and then later needed to upgrade it to Hobby Basic ($9/month, limit 10,000,000 rows).

After assigning the new database, I had two databases attached to the application. They looked something like this:

  • HEROKU_POSTGRESQL_OLIVE (postgresql-dimensional-3321) Old, free-tier (Hobby Dev) database

Fix NVM to use from root (or sudo)
# StackOverflow: http://stackoverflow.com/questions/21215059/cant-use-nvm-from-root-or-sudo
# Source: https://www.digitalocean.com/community/tutorials/how-to-install-node-js-with-nvm-node-version-manager-on-a-vps
# The below command seems to fix the problem
n=$(which node);n=${n%/bin/node}; chmod -R 755 $n/bin/*; sudo cp -r $n/{bin,lib,share} /usr/local
# The above command is a bit complicated, but all it's doing is copying whatever version of node
# you have active via nvm into the /usr/local/ directory (where user installed global files should
# live on a linux VPS) and setting the permissions so that all users can access them.

var [a, b] = [1, 2];
console.log(a, b);
//=> 1 2
// Use from functions, only select from pattern
var foo = () => [1, 2, 3];
