 Handy commands for dumping and restoring Postgres databases.
 
-::: info
+:::info
 Most of these commands are run using Docker as then we don't need to have Postgres installed locally.
 
 If a different version of Postgres is needed, just change the version number in the Docker image tag.
 :::
 
-## Setup 
-
-Create a pgpass file in the current directory with the following content:
-
-```
-<server>:<port>:<database>:<username>:<password>
-```
-
-::: tip
-Use `*` as a wildcard for any of the fields except for the password.
