{"answer":"Recommended action: Create IVFFlat after loading representative data (or use HNSW, which has no training step); raise maintenance_work_mem or lower lists for the memory error; tune ivfflat.probes / iterative scans for recall.\n\nOption: Rebuild IVFFlat after data load or switch to HNSW [evidence: official_recommended_action]\nApplies when: Indexes created in schema migrations\nSteps:\n1. DROP INDEX idx;\n2. load data\n3. CREATE INDEX ... USING ivfflat ... WITH (lists = rows/1000)\n4. or CREATE INDEX ...
