Database setup

Initial setup, on first connection (replacing hostname, username, port, dbname as required):

$ psql "host={hostname} user={username} port={port} sslmode=require dbname=postgres"
> create database colouringlondon;
> \c colouringlondon
> create extension postgis;
> create extension pgcrypto;
> \q

To run all up migrations:

$ ls ./*.up.sql 2>/dev/null | while read -r migration; do psql < $migration; done;

Or all down migrations in reverse order:

$ ls -r ./*.down.sql 2>/dev/null | while read -r migration; do psql < $migration; done;

-- join users against categories and access levels
