Module schema 

Embedded database migrations and schema version tracking.

Migrations are defined as SQL strings and executed in order at startup when [database].run_migrations = true. The schema_version table tracks which migrations have been applied.

Each migration is idempotent: CREATE TABLE IF NOT EXISTS and CREATE INDEX IF NOT EXISTS are used throughout so that re-running migrations on an already-initialized database is a no-op.

Dialect-specific constants are selected at runtime based on DbKind.

Constants

SCHEMA_VERSION

Current schema version. Increment this when adding new migrations.

Functions

run_migrations

Run all pending migrations.
