I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

Why

If, for some reason, you do not want to install PostgreSQL using Homebrew.

Steps

1. Download PostgreSQL source
2. Compile and install PostgreSQL
3. Create a postgres user from terminal
4. Initialize the database

Note: Based on this tutorial.

Why

There exists a _postgres account, but I could not switch to it. My solution so far is to create a postgres account to run the PostgreSQL process.

Steps

sudo dscl . -create /Groups/postgres

sudo dscl . -create /Groups/postgres PrimaryGroupID 1000

Requirements

• PostgreSQL source

Steps

Create a destination directory:

sudo mkdir -p /opt/local/pgsql

def balance(chars: List[Char], open: Int): Boolean = {
  if (chars.isEmpty)
    open == 0
  else if (chars.head == '(')
    balance(chars.tail, open + 1)
  else if (chars.head == ')' && open > 0)
    // found an unmatched '(' earlier
    balance(chars.tail, open - 1)
  else
    balance(chars.tail, open)
