http://developer.postgresql.org/docs/postgres/catalog-pg-trigger.html
says "currently unused" and a desultory search through the sources
confirms that.  I imagine it was put there with the intent of adding
column info later on.  However, being a fixed-width array, I don't
actually see that it would be useful for anything much ... you'd at
least want to change it to a normal array.

BTW, if you don't have a convenient way of grepping the entire PG
source tree and quickly viewing all the hits on a particular symbol,
I *highly* recommend setting up something that can do that.  I use
emacs + glimpse but there are probably newer tools out there.
