Nope.  Unless you use the new SAVEPOINT stuff, the explicit
transaction is the transaction.  Any error in any function will
rollback the whole thing.  The commit happens at the explicit commit.

Every SQL statement (such as calling a function) runs in an implicit
transaction.  Explicit transactions effectively "group" these implicit
transactions such that any one failure causes them all to fail.
