here is a simple golang server illustrating usage of this library

db migrations integration

we use go-migrate to give an example of embedding db-migrations sql scripts inside a server deployment.

You can check the postgres tutorial for go-migrate to gent more information.

inside this directory on your shell just use something like :

migrate create -ext sql -dir db/migrations -seq create_demo_type_table

will create those two files in the db/migrations directory:

000001_create_demo_table.down.sql
000001_create_demo_table.up.sql

then you can enter the corresponding up and down sql code.

whatever sql migrations are present on the db/migrations directory
will be used by the code near line 190
