Summary#
PostgreSQL planner control
Problem#
A developer wants to disable PostgreSQL query optimization entirely to inspect or force a simpler execution path.
Solution#
You cannot execute a PostgreSQL query without a plan, so the optimizer cannot be fully disabled. For experiments, constrain planner behavior instead: toggle selected enable_* settings or set join_collapse_limit and from_collapse_limit to 1 to reduce join reordering.
Failure Modes#
- Assuming there is a usable 'default' plan without the optimizer.
- Changing planner GUCs globally can distort unrelated queries and invalidate benchmarks.
- Plans forced for debugging are often not appropriate for production workloads.
