It's not? I agree with Tom here; this is just one of the numerous things 
you can do to screw up your database as a superuser. Why would you LOCK 
the pg_auth table, or any other system table for that matter, in the 
first place? Let alone in a distributed transaction.

FWIW, deleting the files from pg_twophase is safe when the system is 
shut down.
