running a batch script

I am trying to test out a package called phpGrid and I need to run through its tutorial. But there are some "kinks". I am developing on my ubuntu laptop in a docker container. The postgresql I need to test-to is AWS RDS Postgresql.  I have an account and Server and can access it with pgAdmin. The install instructs for phpGrid asked me to modify conf.php. In my case I used app.conf which sets up the virtual host. I restarted the containers. Next the tutorial wants me to "run" an sql batch script to create the table. The batch script is pretty mySQL centric. I am attaching it.
