FOR LOOP statements are available in PostgreSQL to iterate over a range of integers, a result set, or the result set of a dynamic query.

A FOR loop in PostgreSQL is a control structure that allows you to execute a block of code repeatedly for a specific number of times or until a specific condition is met. It is useful for performing a set of operations on a collection of data, such as iterating over a table and performing an operation on each row. For example, you could use a FOR loop to iterate over a table of data and insert each row into another table.
