What is read-only function? I don't think Postgres has anything like
that. Functions inherit the privileges of the user that executes them by
default. So if the user is read-only (i.e. has just SELECT privilege),
then the function can't do any writes either.
By definition any function marked stable or immutable is read-only though the system doesn't enforce that user-specified label.
