Walkthrough

The PR updates PostgreSQL JDBC driver version references across multiple integration documentation files to consistently use version 42.7.8, replacing older versions (42.5.4, 42.6.0, and 42.7.1) across Debezium, NiFi, Spark, and Tableau integration guides.

Changes

Learning: CrateDB JDBC driver uses the `jdbc:crate://` protocol scheme but communicates via the PostgreSQL wire protocol on port 5432, just like the PostgreSQL JDBC driver (`jdbc:postgresql://`). Do not confuse the `jdbc:crate://` scheme with other protocol schemes like `crate://` (used by SQLAlchemy dialect for CrateDB) or assume it uses the HTTP endpoint on port 4200.

Learning: In CrateDB integration documentation examples, default connection parameters (user="crate", password="", host="127.0.0.1") are intentionally used to provide working out-of-the-box examples for users with local CrateDB instances, rather than using placeholder values that require customization.

Learning: When connecting to CrateDB using PostgreSQL-compatible drivers like Postgrex (Elixir), the `database` parameter handling may differ from standard PostgreSQL usage because CrateDB has no notion of databases like PostgreSQL does. CrateDB uses schemas to separate concerns instead. The `database` parameter might need to be omitted or handled differently to avoid connection issues.

Learning: The `records.Database("crate://", echo=True)` connection string for CrateDB works with defaults: localhost as host, "crate" as user, and blank password. This is valid and functional code in the records library.
