Hello,

I want to connect to a Postgres database but it requires a TLS certificate. How do I include the TLS certificate when I create credentials to connect to the the database?

Hi @brendonGS , looks like we’re in touch over email. For the public record, this would need an adjustment to how the client is created in `language-postgres`.

Looks quite doable:

1. [SSL – node-postgres](https://node-postgres.com/features/ssl)
2. [language-postgresql/src/Adaptor.js at master · OpenFn/language-postgresql · GitHub](https://github.com/OpenFn/language-postgresql/blob/master/src/Adaptor.js#L46-L67)

For use on platform, I’ll also extend the credential form for the postgres adaptor so you can add in cert strings.
