Could you double-check this page? https://docs.snowplow.io/docs/first-steps/querying/?offering=opensource

A couple of things I noticed:

• The page mentions postgres_db_address, but here you have postgres_db_ip_address. Are they meant to be different on AWS and GCP (e.g. because the AWS one is a domain name?) If so we should mention both.
• The BigQuery database used to be <prefix>_snowplow_db and is now <prefix>_pipeline_db. I kinda prefer the old name... But in any case needs changing either here or in Terraform. It is also mentioned on this page.

Indeed on GCP its an IP address instead of a domain name. Both should be mentioned yes!

EDIT: Have now made it postgres_db_address everywhere instead to simplify things.

The BigQuery database used to be _snowplow_db and is now _pipeline_db. I kinda prefer the old name... But in any case needs changing either here or in Terraform. It is also mentioned on this page.

In fact it was already pipeline_db in the default pipeline deployment (secure had snowplow_db so normalized it). Happy to revert back to snowplow_db though.

EDIT: Have now reverted back to _snowplow_db everywhere for BigQuery dataset.
