In this PostgreSQL tutorial, I have explained how to use the rank() function in PostgreSQL, which allows you to assign a unique rank to rows within a specified partition. Also, I have explained the function's syntax and demonstrate its use with practical examples. Additionally, I have discussed the PARTITION BY clause, which can be used in conjunction with the rank() function to divide the rows into partitions based on specific columns.

I have covered the following topics:
1. What is a rank() function?
2. PARTITION BY clause in rank() function
