[postgis-devel] Dump code question

[Obe, Regina]

I was looking at lwgeom_dump.c code trying to understand how the whole stack model it uses works.

There is one thing I came across I don't quite understand.  In
LWGeom_dump and LWGEOM_dump_rings

We do this

		/* allocate a slot for a tuple with this tupdesc */
		slot = TupleDescGetSlot(tupdesc);

		/* allocate a slot for a tuple with this tupdesc */
		slot = TupleDescGetSlot(tupdesc);

Is there a reason for setting this twice?

Thanks,
Regina
