Set ptrace permissions (need to later change this to make pyflame launch the child process)

Postgres setup

sudo -u postgres -i
mkdir ~/postgres_data
/usr/lib/postgresql/10/bin/pg_ctl -D ~/postgres_data -l postgres.log start
psql
CREATE DATABASE feedback_driven_development;
CREATE ROLE metric_backend WITH PASSWORD 'imperial';
\d
vim postgres_data/pg_hba.conf

Now add these lines as the first entry in the file:

local   feedback_driven_development metric_backend              md5

This allows you to connect to postgres using a local unix socket.

host    feedback_driven_development metric_backend 0.0.0.0/0    md5

This allows you to connect to postgres from any host. Now we actually need to make postgres listen on any host:

vim postgres_data/postgresql.conf

Change the listen_addresses line to * or 0.0.0.0 to make it listen on all IP interfaces.

/usr/lib/postgresql/10/bin/pg_ctl -D ~/postgres_data -l postgres.log restart

You might also have to open a 5432 ingress port on CloudStack VM to allow your machine to connect to the postgres database when developing locally
