- migrations/postgres/: consolidated pg schema with tsvector FTS, CITEXT usernames, native CHECK constraints, native BOOLEAN/TIMESTAMPTZ types - db/queries/postgres/: 14 sqlc query files dialect-translated from sqlite ($N placeholders, NOW(), TRUE/FALSE, ON CONFLICT DO UPDATE, RETURNING id, :execrows for mutations needing row count) - sqlc.yaml: second engine entry -> pgdbgen package under pgx/v5 - Makefile: sqlc-verify covers both dbgen + pgdbgen - store/postgres.go: PostgresStore behind //go:build postgres, full Store interface (112 methods). Connection lifecycle real; query methods stub ErrPostgresNotImplemented awaiting pgdbgen wrappers - config: DatabaseConfig.Type/Host/Port/User/Password/Name/SSLMode/MaxConns - main.go: explicit dispatch on database.type; postgres errors with clear pointer at remaining work until pgdbgen + boundary refactor land - phase-a-foundation.md: implementation status + actionable TODO checklist including forward-only sqlite->postgres data migration design
