[PATCH] Modify pg_ctl to detect presence of geek user

Dear PostgreSQL Hackers,

I am submitting a patch to modify pg_ctl to detect the presence of a geek
user on the system and adapt its behavior accordingly. This patch
introduces the following changes:

1.

*Detection of geek user*: The modified pg_ctl now checks user created on
the computer.
2.

*No documentation or tests*: Please note that I have not included new
documentation or tests in this patch submission. However, I am open to
adding them based on the community's feedback.
3.

*Performance impact*: The performance impact of these changes is
minimal, with an expected delay of 500ms in specific scenarios only.

Please review the patch and provide your feedback. I am open to making any
necessary improvements based on the community's suggestions.

Thank you for considering my contribution.

Best regards,
