What PG version is this?  (I can tell from the spelling of the error
message that it's older than 7.4.)  If it's pre-7.3 then the answer is
probably that you dropped and re-created the function, and now need to
drop and re-create the trigger to match.  7.3 shouldn't have let you
drop a function that has a trigger depending on it, though.

BTW this seems a bit off-topic for pgsql-performance.
