Examining index usage for an individual query is done with the EXPLAIN command; its application for this purpose is illustrated in Section 14.1. There are multiple links to scripts that will help you find unused indexes at the PostgreSQL wiki. The basic technique is to look at pg_stat_user_indexes and look for ones where idx_scan , the count of how many times that index has been used to answer queries, is zero, or at least very low.

Everybody knows that one! Monitoring these system-level metrics can help ensure that PostgreSQL has the resources it needs to respond to queries and update data throughout its tables and indexes.
