`EXPLAIN` is a command used to analyze and understand how PostgreSQL executes a query. It provides details about the query execution plan, including which indexes are used and the estimated cost of different operations. For example, running `EXPLAIN SELECT * FROM employees WHERE id = 1;` will show you the query plan and help identify performance bottlenecks or inefficiencies in your SQL queries.
