MigrationLedger over the package-owned pg Pool: ensure() creates the
schema_migrations table (version text PRIMARY KEY, applied_at timestamptz
NOT NULL DEFAULT now()) with idempotent DDL; record() inserts an applied
migration with a parameterized, idempotent statement (ON CONFLICT DO
NOTHING — a rerun never double-applies); has()/applied() read the ledger
back in apply order. Re-exported from the driver boundary (src/index.ts)
so no other package needs the pg driver to touch migration state.
- packages/database-postgres (@personal-blog/database-postgres): the single
workspace package allowed to import the PostgreSQL driver — declares pg and
kysely as exact dependencies (@types/pg for types) and its src/index.ts
imports and re-exports the driver pieces (Pool, Kysely, PostgresDialect) so
the isolation is real, not a placeholder
- pnpm-lock.yaml: importer for packages/database-postgres plus the resolved
pg/kysely dependency tree (frozen-lockfile install keeps working)
- .gitea/workflows/ci.yml: new database-postgres-imports job runs
tests/database-postgres-imports.test.mjs on every PR so the isolation
criterion gates merges
