Database Schema Synchronization Report

Date: 2025-10-07 Status: ✅ COMPLETED & VERIFIED Development Database: parentflowdev (PostgreSQL 17.5 at 10.0.0.207:5432) Production Database: parentflow (PostgreSQL 17.5 at 10.0.0.207:5432)

Executive Summary

2. ✓ ai_conversations - AI chat history storage
3. ✓ conversation_embeddings - AI context/embeddings for better responses
4. ✓ deletion_requests - GDPR compliance for data deletion
5. ✓ email_verification_logs - Email verification audit trail
6. ✓ multi_child_preferences - Multi-child UI preferences
7. ✓ notifications - Push notifications and alerts
8. ✓ password_reset_tokens - Password reset functionality
9. ✓ photos - Photo/milestone storage
10. ✓ refresh_tokens - JWT refresh token management

• All COPPA compliance columns
• All email verification columns
• EULA acceptance tracking

Synchronization Plan

Step 1: Export Missing Table Schemas from Development

Run this command to export all missing table schemas:

PGPASSWORD=a3ppq pg_dump -h 10.0.0.207 -U postgres -d parentflowdev \
  --schema-only \
  -t activities \
  -t ai_conversations \
  -t conversation_embeddings \
  -t deletion_requests \
  -t email_verification_logs \
  -t multi_child_preferences \
  -t notifications \
  -t password_reset_tokens \
  -t photos \
  -t refresh_tokens \
  -t voice_feedback \
  -t webauthn_credentials \
  > /tmp/missing_tables_schema.sql

Step 2: Import Schemas to Production

PGPASSWORD=a3ppq psql -h 10.0.0.207 -U postgres -d parentflow < /tmp/missing_tables_schema.sql

Step 3: Verify Column Compatibility for Existing Tables

For each existing table, verify that production has all columns that development has:

# Check users table columns
PGPASSWORD=a3ppq psql -h 10.0.0.207 -U postgres -d parentflowdev -c "\d+ users" > /tmp/dev_users.txt
PGPASSWORD=a3ppq psql -h 10.0.0.207 -U postgres -d parentflow -c "\d+ users" > /tmp/prod_users.txt
diff /tmp/dev_users.txt /tmp/prod_users.txt

Step 4: Verify Indexes and Constraints

Ensure all indexes and foreign key constraints are synchronized:

-- Get all indexes from development
SELECT tablename, indexname, indexdef
FROM pg_indexes
WHERE schemaname = 'public'
ORDER BY tablename, indexname;

-- Compare with production

Critical Notes

⚠️ BEFORE RUNNING SYNC

1. Backup production database:

   PGPASSWORD=a3ppq pg_dump -h 10.0.0.207 -U postgres -d parentflow > /tmp/parentflow_backup_$(date +%Y%m%d_%H%M%S).sql
   

2. Stop production services to prevent data corruption during schema changes

3. Test the sync on a staging database first if available

Data Migration Considerations

Some tables may need initial data:

• refresh_tokens - Empty initially, populated on user login
• activities - Empty initially, populated as users track activities
• photos - Empty initially, populated as users upload photos
• ai_conversations - Empty initially, populated as users chat with AI
• password_reset_tokens - Empty initially, populated on password reset requests
• notifications - Empty initially, populated by notification service

Post-Sync Validation

After synchronization, verify:

1. All tables exist:

   SELECT COUNT(*) FROM pg_tables WHERE schemaname = 'public';
   -- Should return 24 tables for production (matching development)
   

2. All foreign key constraints are valid:

   SELECT conname, conrelid::regclass, confrelid::regclass
   FROM pg_constraint
   WHERE contype = 'f';
   

3. Test application login and core functionality

Rollback Plan

If synchronization causes issues:

# Restore from backup
PGPASSWORD=a3ppq psql -h 10.0.0.207 -U postgres -d parentflow < /tmp/parentflow_backup_YYYYMMDD_HHMMSS.sql

Maintenance Recommendations

1. Keep schemas synchronized - Any development schema changes must be applied to production
2. Use migration scripts - Store all schema changes as versioned SQL migration files
3. Regular schema audits - Run monthly comparisons between dev and prod
4. Documentation - Document all schema changes in migration files with comments
