Re: drop function all - ?

this seems like an unlikely solution since i don't think it is in any
sql spec... in the mean time you could create a function that loops
through pg_proc and drops functions based on the function attributes.
check the docs for info on data in pg_proc if you do. btw, the error
messages in 7.4 are improved to help with this case.
