I was trying to limit unnecessary whitespace changes.  s/ereport/econfess/ leaves the function name nearly the same length such that the following lines of indented error text don't usually get moved by pgindent.  Given the unpopularity of the name, it's not worth it, so I'll go with Robert's report_corruption, instead.
