I don't think that the problem is that people are accidentally typing
"pg_resetxlog $PGDATA" and pressing return. They're typing that on
purpose, and if you change the sequence of characters required to get
that effect, they'll just type the new thing instead. The problem is
that they don't understand when it's appropriate to use that command
and what the consequences are.
