"create or replace function..." with "security invoker"
(or without "security definer" since security invoker
is the default) is probably another way to do it, but
it would be slower than "alter function" since it needs
to parse the code again. That might matter if you have
many functions to change.
Bear in mind that things might break with such a change.
There might be a reason that the functions needed to be
created as security definers. I'd recommend checking
each function's need to be a security definer before
changing it (or just test it thoroughly somewhere).
cheers,
