pongo shell command does not launch Postgre SQL docker instance

[pravynandas]

Inside pongo shell environment, when I run a spec test using 'busted', I get below error:

[PostgreSQL error] failed to retrieve PostgreSQL server_version_num: host or service not provided, or not know

Turned out, when running pongo shell command, the postgresql docker instance not being launched. It only launched the kong docker instance.

Fix: Run pongo run command first followed by pongo shell.
