# Dump and Restore
|
|
|
|
Handy commands for dumping and restoring Postgres databases.
|
|
|
|
::: 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.
