Observe the list of "Files changed this run" at
http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=gazelle&dt=2006-06-17%2000:30:01
The links to the core-system files are OK but the plpgsql files are not
correct, egpgsql/src/gram.y 1.93
where it should bepgsql/src/pl/plpgsql/src/gram.y 1.93
I'm betting on an overly-greedy regex ...
