* Server-side safety net for runaway queries and abandoned transactions:
* - `statement_timeout=90000` kills any single statement still running
* after 90s. Protects against pathological queries.
* - `idle_in_transaction_session_timeout=90000` kills a session that has
* opened a transaction and gone idle for 90s. Protects against
* transactions that hold row locks while waiting on external I/O.
*
* These are last-resort caps — application code should never approach
* them. Migrations or admin scripts that legitimately need longer limits
* must construct their own client with overrides.
