Connecting to Heroku #23

Summary

I'd like to connect to a Postgres instance running in Heroku.

Additional context

I use Heroku's DATABASE_URL environment variable, with the suffix ?ssl=1 in my connectionString. When I run gatsby develop I get this error:

For more information on this error, see: https://github.com/brianc/node-postgres/issues/2009

Indicating the right SSL certificate using the ?sslrootcert=... option should work, but it's kind of finicky to get it to work. I had success on Node 12 doing this, but on Node 14 not so much.

Since we're using a connection string, we can't just add rejectUnauthorized: false (though you could try it with ?rejectUnauthorized=0 or similar, I suppose).

I recently raised this PR against pg-connection-string to allow for parsing ?sslmode=no-verify, but I'm not sure if it's released yet: https://github.com/brianc/node-postgres/pull/2345

Another option is to disable Node's TLS validation; e.g.:

process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0;

Ultimately this is an issue between the pg module, your Node version, your server's trusted SSL certificates, and your database server. gatsby-source-pg has very little say in the matter.
