Dissecting Tuples in C

I am trying to get up to speed writing C triggers and I have a question about the relation between HeapTuples and
othertuple-related types, like TupleTableSlots, and the routines and macros used to manipulate them. I am reading and
re-readingthe online docs, but still have some broad questions.<br /><br /> For example, suppose I just wanted a
triggerto iterate through the HeapTuple pointed at by the tirgger data tg_trigtuple, printing out the column names,
types,and values (lets say, only ints and strings for simplicity). How would I do this?<br /><br /> A pointer to a good
documentwould be just as good as a detailed answer.<br /><br /> Thanks!<br /><br /><table cellpadding="0"
