How to access the database

Use PgAdmin, which can connect to the DB through Railway’s internal network and limits login retries for safety.

Passwords are stored in Railway. Hosted in the following locations for each environment

• Dev: https://pgadmin.maps.slabs-dev.org/browser/
• Staging: to be set up
• Prod: to be set up

S3 Bucket

Will created schemas in the dataflow folder.
