-- Migration to apply specific autovacuum settings to high-traffic tables

-- This is crucial to prevent table and TOAST bloat for 'embeddings' and 'chunks'

-- Tuning for the 'embeddings' table
|
|
-- Default scale factor (0.2) is too high, leading to infrequent vacuuming.
|
|
-- Lowering to 2% to ensure frequent cleanup.
