Common examples include <code>pg_stat_statements</code> for query performance tracking, <code>uuid-ossp</code> for UUID generation, <code>postgis</code> for geographic data, and <code>pg_trgm</code> for fuzzy text search.</p> <p>Before modifying a database or diagnosing unexpected behavior, it is useful to know exactly which extensions are installed, which versions are running, and which schema their objects live in.</p>
