In PostgreSQL, you can use the SUBSTRING function to retrieve specific characters at a given index position within a string. Here is an example:

SELECT SUBSTRING('Hello, World', 7, 1) AS character_at_index;

In the example above, the SUBSTRING function will return the 7th character in the string “Hello, World”, which is ,. You can replace the string and index as needed to get the character you want.
