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.
Option: Rebuild IVFFlat after data load or switch to HNSW [evidence: official_recommended_action]
Applies when: Indexes created in schema migrations
Steps:
1. DROP INDEX idx;
2. load data
3. CREATE INDEX ... USING ivfflat ... WITH (lists = rows/1000)
4. or CREATE INDEX ... USING hnsw ...
Expected: Normal recall
Evidence basis (self-declared by the contributing chat client): untested.
