# the following command should return a JSON array with just all packages visible for the admin of the customer aab:

The latter `curl` command actually goes through the database server.

'mike@hostsharing.net' and 'sven@hostsharing.net' are Hostsharing hostmaster accounts coming from the example data which is automatically inserted in Testcontainers and Development environments.
Also try for example 'admin@aaa.example.com' or 'unknown@example.org'.

If you want a formatted JSON output, you can pipe the result to `jq` or similar.
If you still need to install some of these tools, find some hints in the next chapters.

It's best to run `pg-sql-reset && gw bootRun` before each test run, to have a clean database.
## How to Amend Liquibase SQL Changesets?
Liquibase changesets are meant to be immutable and based on each other.
That means, once a changeset is written, it never changes, not even a whitespace or comment.
Liquibase is a *database migration tool*, not a *database initialization tool*.
This, if you need to add change a table, stored procedure or whatever,
create a new changeset and apply `ALTER`, `DROP`, `CREATE OR REPLACE` or whatever SQL commands to perform your changes.
These changes will be automatically applied once the application starts up again.
This way, any staging or production database will always match the application code.
But, during initial development that can be a big hassle because the database structure changes a lot in that stage.
Also, the actual structure of the database won't be easily recognized anymore through lots of migration changesets.
Therefore, during initial development, it's good approach just to amend the existing changesets and delete the database:
```shell
pg-sql-reset
gw bootRun
```

Just don't forget switching to the migration mode, once there is a production database!
