You can't... the function is already running within a transaction (implicit
or explicit) and PostgreSQL doesn't have any nested transactions, therefore
you can't start a transaction from within a function.

I'm not sure what you're trying to do, but I think SELECT ... FOR UPDATE
would work in this context.
