Tom,
Just for testing, I stuffed it into ExecEvalVar under the switch statement in execQual.c. This was a chosen spot I was
fairlycertain I could get some kind of output.
TupleTableSlot *slot;
TupleDesc tuple_type;
The above portion is actually part of the delivered source code.
Maybe I need to as you said wrap a NameStr() around it?
Thanks

questionis how to effectively break down a TupleTableSlot into it's properties. I've been messing around with it for
hoursnow and thought the code below would return the attribute name for table but instead just returns some binary
info.
The code looks ok as far as it goes ... it's not using NameStr() which I
would consider good style, but that's just cosmetic.
What context is this being called in, and where are you getting the slot
from? I think you're probably not really using a valid slot ...
