+# Run SQL Against Remote Postgres Database
+
+You can access a remote Heroku PostgreSQL database through a `psql` session
+using the following command:
+
+```bash
+heroku pg:psql --app my-app
+```
+
+That opens an interactive psql session.
+
+If instead you'd like to run a single SQL script against that remote database,
+you can redirect that script to the connection.
+
+```bash
+heroku pg:psql --app my-app < query.sql
+```
+
+The results of running that SQL will be written to stdout.
+
+You can take this a step further by redirecting the output into another file so
+that you can review and search the results at your convenience, rather than
+only having them appear in your terminal.
+
+```bash
+heroku pg:psql --app my-app < query.sql > results.out
+```
