+# Open Heroku Database In Postico From Terminal
+
+I recently downloaded [Postico](https://eggerapps.at/postico/) at the
+recommendation of [Dillon Hafer](https://dillonhafer.com/). I tend to use
+`psql` as a PostgreSQL client for all my database querying needs. However,
+Dillon highly recommended Postico for doing system admin querying.
+
+I needed to connect directly to a production Postgres server on Heroku to
+investigate slow queries. Postico presented me with a form of individual fields
+for host, port, username, password, database, etc.
+
+This would have been a little annoying to fill in manually. Dillon had a
+shortcut to recommend. From the command line you can open Postico with a
+connection string. It knows how to split that connection string into the
+respective fields.
+
+```bash
+heroku config:get DATABASE_URL --app APP_NAME | xargs open -a Postico
+```
+
+This requests the `DATABASE_URL` from Heroku. It is a Postgres connection
+string with all the fields needed to connect to a remove server. This is then
+passed via `xargs` to `Postico` as it is being `open`ed.
