This module provides functions creating a temporary postgres instance on a random port for testing.

result <- start []
case result of
  Left err -> print err
  Right tempDB -> do
    -- Do stuff
    stop tempDB

The are few different methods for starting postgres which provide different methods of dealing with stdout and stderr.

The start methods use a config based on the one used by pg_tmp (http:/ephemeralpg.org), but can be overriden by different values to the first argument of the start functions.

MacOS and Linux are support. Windows is not.

Requires PostgreSQL 9.3+

WARNING!! Ubuntu's PostgreSQL installation does not put initdb on the PATH. We need to add it manually. The necessary binaries are in the /usr/lib/postgresql/VERSION/bin/ directory, and should be added to the PATH

echo "export PATH=$PATH:/usr/lib/postgresql/VERSION/bin/" >> /home/ubuntu/.bashrc
