You must answer without claiming live web access.

Topic: For a small platform team running SQLite today, should they migrate primary OLTP storage to PostgreSQL or stay on SQLite + Litestream-style replication when the workloads are:

• user accounts
• subscriptions
• audit logs
• real-time auction transactions
• Discord bot state

Provide a balanced recommendation.

Requirements:

• Separate facts/general engineering principles from context-dependent decisions.
• Explain trade-offs in data consistency, schema flexibility, querying, operations, and scaling.
• Give a final recommendation for the described use case.
• Include 3 risks or situations where your recommendation could be wrong.
• Do not cite specific statistics, articles, or company claims unless you can verify them.
• In the comparison object, put PostgreSQL points under postgresql and SQLite/Litestream points under mongodb (schema key retained for validator compatibility; treat mongodb as the SQLite+Litestream side).

Output format: { "executive_recommendation": "...", "comparison": { "postgresql": ["...", "..."], "mongodb": ["...", "..."] }, "workload_analysis": { "user_accounts": "...", "subscriptions": "...", "audit_logs": "...", "auction_transactions": "...", "discord_bot_state": "..." }, "risks_and_exceptions": ["...", "...", "..."] }
