 You can quickly test the PostgreSQL / MySQL scripts using `postgres.sh` / `mysqld.sh` / `mariadb.sh` in the [DevOps Bash tools](https://github.com/HariSekhon/DevOps-Bash-tools) repo, which boots a docker container and drops straight in to a `mysql` / `psql` shell with this directory mounted at `/sql` and used as `$PWD` for fast easy sourcing eg.
 
 postgres:
-```
+
+```postgres-sql
 \i /sql/postgres_query_times.sql
 ```
-```
+
+```postgres-sql
 \i postgres_query_times.sql
