PostgreSQL Index Usage Analysis

Question

Is there a tool or method to analyze Postgres, and determine what missing indexes should be created, and which unused indexes should be removed? I have a little experience doing

Answer 1

PoWA seems like an interesting tool for PostgreSQL 9.4+. It collects statistics, visualizes them, and suggests indexes. It uses the pg_stat_statements extension.

PoWA is PostgreSQL Workload Analyzer that gathers performance stats and provides real-time charts and graphs to help monitor and tune your PostgreSQL servers. It is similar to Oracle AWR or SQL Server MDW.
