Thread: Using information_schema to find about function parameters?

I looked at the information_schema.routines, to get information about
the functions in the database, but there doesn't seem to be a way to
extract the parameters information about functions? Where would I seek
for such information?

They are stored as an array in pg_proc (proargnames, proallargtypes)
