Quickly prototype a Postgresql database via Docker, and serve its SchemaSpy results via Nginx

When prototyping a new database from its initializing SQL code, and wanting to examine details of its relational architecture or demonstrate it to others, it's really convenient to pull my aganse/quick_postgresql repo. I just pop in my table creation lines in init.sql, make run, and view the interactive SchemaSpy website generated at its internal port. As the database sticks around and grows into use, still it's really helpful as it evolves to be able to keep rerunning and updating that SchemaSpy website as a standard part of the workgroup toolset.
