pub const DB_SYSTEM: &str = "db.system";

The database management system (DBMS) product as identified by the client instrumentation.

The actual DBMS may differ from the one identified by the client. For example, when using PostgreSQL client libraries to connect to a CockroachDB, the db.system is set to postgresql based on the instrumentation's best knowledge.
