Firebird 6 (protocol 20, schemas)

Against an FB6 server the driver negotiates protocol 20 automatically (inline blobs included), and the new attach-time options are exposed:

// Schema search path — how unqualified names resolve (FB6 default: PUBLIC, SYSTEM)
const db = await connect({ host, database, searchPath: ['APP', 'PUBLIC'] });
await db.query('select * from settings');   // finds APP.SETTINGS

// Create a database owned by another user
await createDatabase({ host, database, owner: 'APP_OWNER' });

Both options are silently ignored by pre-FB6 servers, so they're safe to set in configs shared across versions.

What Firebird 6 adds

The headline SQL-level features (all exercised by the driver's test suite and the demo dashboard's feature explorer against the firebirdsql/firebird:6-snapshot image):

• SQL schemas — CREATE SCHEMA, qualified names, CURRENT_SCHEMA, and a schema search path inside one database.
• CAST … FORMAT — format and parse datetimes with Oracle-style masks.
• GREATEST / LEAST / BTRIM — row-wise min/max and trim-any-character.
• ANY_VALUE — pick an arbitrary representative per group.

Tracked continuously

FB6 support is tracked against the firebirdsql/firebird:6-snapshot image in CI (the same suite as FB3/4/5); a canary test watches for the arrival of upstream JSON support.

Snapshot status

Firebird 6 is pre-release. The driver targets the current snapshot protocol (20) and follows changes as they land upstream.
