BQ now supports FK & PK; take into account for diagrams 🙏

[MaximusMcCann]

You can now define Foreign and Primary keys on table columns in BigQuery. Would love to see them interpreted and added to the lovely image output to see connections between tables.

Google docs regarding adding FK and PK constraints.

Queries to pull the information off the schema about FK & PK.

SELECT *
FROM <PROJECT_ID>.<DATASET>.INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE;

SELECT *
FROM <PROJECT_ID>.<DATASET>.INFORMATION_SCHEMA.KEY_COLUMN_USAGE;
