-- Garmin Personal API (#1333): a per-user key pasted once, a new measurement
-- source for the rows the sync writes, Garmin's own day scores (Body Battery,
-- stress level), and two types a bridge pushes through the ingest token
-- because the Personal API does not carry them (Training Readiness, acute
-- training load).
--
-- One DO block, so the lock wait is bounded and the file is one statement
-- that rolls back whole. Adding an enum value inside a transaction is fine
-- since PostgreSQL 12 as long as the value is not used in it, and nothing
-- here uses them.
--
-- Purely additive: nullable columns, no default, no backfill. IF NOT EXISTS
-- keeps a replay harmless. Enum values cannot be dropped in PostgreSQL, so
-- there is no down path for them; dropping the six columns undoes the rest.
