Task 06: Port Workflow Execution Stores

Summary

Make workflow sync and automation persistence portable. Cover settings, triggers, repositories, runs, and cleanup jobs on PostgreSQL.

In scope

• Build schema statements with portable timestamp types and boolean defaults.
• Rebind workflow sync and automation queries.
• Replace SQLite-only conflict syntax.
• Add fresh, replay, and representative operation tests on PostgreSQL.

Out of scope

• Change workflow synchronization behavior.
• Change automation scheduling or task creation.

Acceptance

• Both stores initialize twice against their PostgreSQL schemas.
• Workflow sync settings and automation lifecycle operations succeed on PostgreSQL.
• Automation read transactions rebind expanded list queries after sqlx.In.

Verification

KANDEV_TEST_POSTGRES_DSN=<dsn> go test -race ./internal/workflowsync ./internal/automation -run 'TestPostgresStore' -v

Files likely touched

• apps/backend/internal/workflowsync/store.go
• apps/backend/internal/workflowsync/store_postgres_test.go
• apps/backend/internal/automation/store.go
• apps/backend/internal/automation/export_store.go
• apps/backend/internal/automation/run_retention.go
• apps/backend/internal/automation/store_postgres_test.go

Dependencies

• Task 05 completes provider store conversion.

Risks

• Automation joins core task tables. Tests must use the real repository startup order for prerequisite schemas.

Parallelism

sequential

Inputs

• Existing workflow sync and automation store tests.
• apps/backend/internal/backendapp/postgres_boot_test.go

Results

• Adapted workflow-sync and automation schema DDL to the active driver, including PostgreSQL timestamp and boolean forms.
• Rebound workflow-sync and automation reads, writes, transactions, dynamic run projections, and retention queries at the executing database boundary.
• Replaced the automation repository backfill's SQLite-only conflict syntax with a portable ON CONFLICT ... DO NOTHING clause.
• Preserved task-state joins and isolated-test fallbacks while using integer predicates for the shared task_sessions.is_primary column.
• Added PostgreSQL fresh/replay coverage for workflow settings, automation repositories, triggers, runs, run summaries, retention checks, and cleanup jobs.
• Verification: KANDEV_TEST_POSTGRES_DSN=<local test DSN> go test -race ./internal/workflowsync ./internal/automation -run 'TestPostgresStore' -v passed.
• Verification: KANDEV_TEST_POSTGRES_DSN=<local test DSN> go test -race ./internal/workflowsync ./internal/automation passed.
