Bug reference: 18201
Logged by: Augusto Camargo
Email address: gutto88(at)gmail(dot)com
PostgreSQL version: 16.1
Operating system: Windows 10
Description:

It looks like the bin\data folder, which is the db cluster folder, has some
kind of structure and on the end of installation i get a POP UP , indicating
that the folder setup for the db clusters was not configured right.

This log i got from C:\Program
Files\PostgreSQL\16\installation_summary.log:
