Nobody claims PostgreSQL is proof against power failures.

You got lucky.  Period.  MSSQL is not proof against power failures,
and neither is NTFS.  In particular, that the database accepted 
transactions afterward is far from proof that its files were not 
corrupted.

Incompetent testers produce invalid tests.  Invalid tests lead to 
meaningless conclusions.  Incompetent testers' employers suffer
from false confidence, and poor decision-making.
