Phase 01 Plan 01: Database Setup Summary

Docker Compose with Postgres 18 + pgvector 0.8.1 and line_item table with pre-allocated embedding columns

Performance

• Duration: 2 min
• Started: 2026-02-20T10:17:10Z
• Completed: 2026-02-20T10:19:01Z
• Tasks: 3
• Files modified: 2

Accomplishments

• Docker Compose configuration with pgvector/pgvector:pg18 image
• Database initialization script enabling pgvector extension
• line_item table with Orcha's booking_history_item structure
• Pre-allocated vector columns for all 3 embedding models (768, 1024, 384 dimensions)

Task Commits

Each task was committed atomically:

1. Task 1: Create Docker Compose configuration - 1a30f6a5 (feat)
2. Task 2: Create database initialization script - f711cb15 (feat)
3. Task 3: Verify database setup - No commit (verification-only task)

Files Created/Modified

• docker-compose.yml - Postgres 18 + pgvector service with healthcheck, port 5433
• init.sql - pgvector extension and line_item table schema with embedding columns

Decisions Made

• Used port 5433 to avoid conflicts with local Postgres (standard port 5432)
• Pre-created nullable embedding columns to avoid schema migrations in Phase 2
• Used Postgres 18 PGDATA path /var/lib/postgresql/18/docker (changed from /data in Postgres 18)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Database foundation complete, ready for Plan 02 (Python environment + data import)
• Container can be started with docker compose up -d
• Database accessible at localhost:5433 with dev/dev credentials

Phase: 01-foundation Completed: 2026-02-20
