I have a slow SQL query against [DB ENGINE — Postgres / MySQL / SQL Server]. The query and the EXPLAIN plan are below. Walk through the plan step by step, identify the most expensive operations, and propose 3 optimization options ranked by likely impact and effort. For each option, show the rewritten query and the index/migration that needs to ship first. Predict the new plan shape if possible. Don't guess at table sizes — ask me before assuming.
