​The 9.4 documentation is in direct conflict with this statement...all
persistent updates inside the associated BEGIN/END block should be rolled
back.

Transactions MUST start "outside your function" by definition. By not
re-throwing the exception any outer block (i.e., the one calling the
function) would still end up intact but every statement inside of the
function should rollback unless separate blocks are created to isolate the
different statements.
