Well, the manual doesn't seem to reflect that fact.
If that's how the developers feel about rules, i.e they can't be
bothered to make any changes to the rules code any more, no matter how
minor (e.g. this TRUNCATE issue), then you should explicitly state in
the manual that they are depreciated, and stop making stupid
statements like "so if many rows are affected in one statement, a rule
issuing one extra command is likely to be faster than a trigger" that
encourage people to use rules !
