Bug reference:      18779
Logged by:          Daniel Elishakov
Email address:      dan-eli@mail.ru
PostgreSQL version: 16.6
Operating system:   Debian GNU/Linux 12 (bookworm)
Description:       

This bug takes place in Debian-based operating systems. To replicate this
bug please do following:
1) Install and initialize PostgreSQL dbms

I think we need more details. There are multiple ways to do both of those things.
 
2) Switch user to root (sudo -i)
3) Switch user to postgres

What if you just use one command, sudo -i -u postgres?
 
4) run command psql -U postgres -h localhost (may run multiple times to see
the bug)

Looks like this bug occurs because root user has ENV variable KRB5CCNAME,
while postgres does not.

What did you do to make this happen?  A default debian installation does have KRB5CCNAME set for root.

Cheers,

Jeff
