## Usage
First, start a postgres container:
```bash
$ docker run --rm -d --name postgres -p 5432:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=mypass -e POSTGRES_DB=postgres postgres:13
d1a2eb0fb44da9c3488184f5296da28d1c7f88bd32bd4ec81fc254f006886b03
```
Start the server:
```bash
$ POSTGRES_URL=postgresql://postgres:mypass@localhost:5432/postgres?sslmode=disable go run main.go
...
{"level":"info","msg":"Serving gRPC on [::]:8080"}
{"level":"info","msg":"Serving Web UI on http://0.0.0.0:8080"}
```
Navigate to http://0.0.0.0:8080 to see the auto-generated web UI for the
service, courtesy of gRPC reflection and

## Usage with Cockroach DB
The application also supports talking to a Cockroach DB instance, by using the `cockroachdb` scheme:
```
cockroachdb://user:password@host:5432/defaultdb
```
The scheme is used when performing the database migrations, as the behaviour changes based on the database.
## Developing
### Requirements
* `go` > 1.16
### Making changes
After making any changes to the proto file or the migrations, make sure to
regenerate the files:
```bash
$ make generate
```
If you want to change the schema of the database, add another migration file.
Use the same naming format, with the new file names starting `2_`. Make sure to
run `make generate` and increment the migration version in `users/helpers.go`.
