Lateral Join in PostgreSQL

Lateral join allows you to reference columns from preceding tables in a query, making it possible to perform complex operations that involve correlated subqueries and the application of functions on tables in a cleaner and more effective way. The LATERAL keyword in PostgreSQL is used in conjunction with a subquery in the FROM clause of a query. It helps you to write more concise and powerful queries, as it allows the subquery to reference columns from preceding tables in the query.
