Stored functions already execute inside the context of some
already-running transaction. You don't run multiple transactions
inside a function.
Further, when this is a trigger function, there is a very clear
transaction with which the activity of the trigger is already
associated. If you were to start another transaction at the point
where you try to do so, that would break the processing of any further
triggers that might run after this one...

Oddly enough, this is completely standard behaviour for shells. This
is a roundabout way of saying `don't use combined chains of `&&'s and
`||'s unless you think Gödel's theorem is for sissies'.
