Came across this comment in execTuples.c...
*In the implementation of nested-dot queries such as
*"retrieve (EMP.hobbies.all)", a single scan may return tuples
*of many types, so now we return pointers to tuple descriptors
*along with tuples returned via the tuple table. This means
*we now have a bunch of routines to diddle the slot descriptors
*too. -cim 1/18/90
Hmm. Another few years of reading the source and I'll probably
understand all this :-) :-(.
Can anybody provide any insight? Like What EMP.hobbies.all meant in
postquel?
