PostgreSQL

Installation

1. Install package

   If you are developing with binary, the package is already bundled in the binary. You can skip this step.

   npm i @vulcan-sql/extension-driver-pg

2. Update vulcan.yaml, and enable the extension.

   extensions:
     ...
     pg: '@vulcan-sql/extension-driver-pg' # Add this line

3. Create a new profile in profiles.yaml or in your profile files. For example:

   - name: pg # profile name
     type: pg
     connection:
       host: example.com
       port: 5432
       user: postgres
       password: some-secret
       database: postgres
