pgsql: Report Python errors from iterators with PLy_elog

Report Python errors from iterators with PLy_elog

This improves reporting, as the error string now includes the actual
Python exception. As a side effect, this no longer sets the errcode to
ERRCODE_DATA_EXCEPTION, which might be considered a feature, as it's
not documented and not clear why iterator errors should be treated
differently.
