Hello,
Sorry for the previous confusing mail ..

iam in need of a function through which i can get a Relation Node given its 
name ..
precisely the same one equivalent to " RelationSysNameGetRelation " .. which 
works for all types of relations (system and user tables)

Won't you have to go get the data from the database for this? I mean
actually execute the query:

Iam trying to test for some patch in the code of the Optimizer(planner) and 
so I need some C functions, which does the job. I think we must have some 
functions like the ones i have mentioned for the purpose. isin't it ??
