Well, first, it doesn't follow PL/pgsql guidelines. You need at least a
BEGIN at the beginning of the function, and an END at the end.

But even with this, you cannot use VACUUM in a function. Don't remember
the reason why right now, but all you'll get is this error:

ERROR:  VACUUM cannot be executed from a function or multi-command
string
