I don't know. It's quite possible, I have not used PostgreSQL 10
extensively in Kali... I rely on Kali users for this.
I just checked and the usual database initialization code does not trigger
any write to pg_twophase so if there's a new fsync() on that directory
without any prior write, it's quite possible that this could fail later
on during PostgreSQL's use.
Cheers,
