-# Connect To A Database By Color
-
-All of your PostgreSQL databases in Heroku are given attachment names that use
-a random color. This might be _pink_, _brown_, _cobalt_, etc. And the
-attachment names then look like `HEROKU_POSTGRESQL_PINK`,
-`HEROKU_POSTGRESQL_BROWN`, `HEROKU_POSTGRESQL_COBALT`, etc.
-
-We can connect to a Heroku-managed PostgreSQL instance from the command-line
-like so:
-
-```bash
-$ heroku pg:psql --app my-app
-```
-
-This is going to connect to the _default_ database which is the one with the
-`DATABASE_URL` attachment.
-
-There are lots of instances where we may have other databases besides the
-primary (e.g. let's say we have a read replica follower). If we want to connect
-to that one, we can do so by _color_.
-
-If that database's attachment is `HEROKU_POSTGRESQL_IVORY`, then we'd connect
-to it like so:
-
-```bash
-$ heroku pg:psql ivory --app my-app
-```
