Hey guys, this is just a quick tip on how to make sure you don't screw up the database connection pool in Go. This might also apply to other languages and frameworks.

Also, regarding writing tests against real PostgreSQL databases, isolated per test and without losing speed, I can recommend to take a look at https://github.com/allaboutapps/integresql - disclaimer, we are the authors.
