regexp_replace
is a function in PostgreSQL that allows you to replace a substring in a string using regular expressions. It takes three arguments: the string, the pattern to match, and the replacement string.

The parts of the code are:
regexp_replace

: the string that contains the substring that needs to be replaced'World'
: the substring that needs to be replaced'PostgreSQL'
: the string that will be used to replace the substring
