# Activate postgres and enable connection to it
# Copies config file that allows user postgres to enter psql shell,
# as shown here: https://stackoverflow.com/a/26735105 (change peer to trust).
# Commented out the start/restart commands because even with running them, postgres isn't running when the container is created.
# So there's no point in starting posgres here if it's not active when the instance opens.
