Oh, I get it. You mean read-committed transaction mode's side-effect inside a transaction block! No, that's not the case. Just confirmed that by issuing a syntactically wrong statement in that session (resulting in ERROR), and then doing 'select 1'; it did not raise the error 'Current transaction is aborted...'. And scrolling back the session does not show any BEGIN/COMMIT/ROLLBACK commands that I would have issued.
