The goal of this project is to be a crowd sourced resource to find out if a product is vegan

    - barnivore lookup
    - alergen ingredient database lookup?

Troubleshooting:

Error:
`2025/04/17 16:21:21 ERROR: relation "idx_user_claims_product_id" already exists (SQLSTATE 42P07)`
Explanation: The database tables already exist and the program was trying to create them again.

Fix: Either don't create the databases again in the code, or run `dropdb veganDB` to allow it to recreate it.

Error:
`psql: error: connection to server at "localhost" (::1), port 5432 failed: FATAL:  database "<user>" does not exist`
Explanation: Postgres automatically tryes to connect to a database with the same name as the user. Specify user and database:
`psql -U username databaseName `




## How to start database

- Run `brew services start postgresql`
- Create database
    - Setting environment variables:
        - PGHOST=localhost
        - DB_NAME=veganDB (Can be arbitrary)
    - Run `createdb veganDB`
(To delete in future just run dropdb <name>)
