Any competent programmer can crash a machine, any competent DBA can
crash a DB, anyone with physical access can unplug a server, or set it
on fire.

Given it is not an easy mistake to make ( "DROP type void" is way more
dangerous, being so simple ), I would consider this anecdotal. I doubt
"survive an hostile DBA" is an objective for postgresql.
