$ psql "host={hostname} user={username} port={port} sslmode=require dbname=postgres"
> create database colouringlondon;

> create extension postgis;
> create extension pgcrypto;
> \q
$ psql "host={hostname} user={username} port={port} sslmode=require dbname=colouringlondon" < 001.create-core.up.sql

GRANT SELECT ON TABLE user_access_levels, user_categories TO appusername;
-- read/write building data
GRANT SELECT, UPDATE ON TABLE buildings TO appusername;
-- read geometry data
GRANT SELECT ON TABLE geometries TO appusername;
-- read/append to logs
GRANT SELECT, INSERT ON TABLE logs to appusername;
-- use id sequences
GRANT USAGE ON ALL SEQUENCES IN SCHEMA public to appusername;
-- use postgis/pgcrypto functions
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO appusername;
