I am not sure what you are proposing here, nor am I sure to what kind
of assertions you are referring to in spi.c. If we were to change the
error reporting, what of the external and existing consumers of this
routine? They would not expect to bump on an exception and perhaps
need to handle error code paths by themselves, no?
Anyway, any callers of SPI_execute() (tablefunc.c, matview.c) we have
now in-core react based on a status or a set of statuses they expect,
so based on that fixing this caller in xml.c sounds fine to me.
