That is the behavior I saw on my Linux box, but the manpage installed
on the same box sez that the return value is equal to the passed buffer
size if there's an overrun. Maybe the manpage is out of date.

Anyway, the fixed code copes with both conventions.

You'll need to re-initdb to get rid of the broken rules in your
database, but then things should be OK...
