Hi all,
When you fire a query in postgresql, it will first parse the query and create the data structures for storing various aspects of the query and executing the query. (Like RangeTblEntry, PlannerInfo, RangeOptInfo etc.).
I want to know how does postgresql stores the join predicates of a query. Like which data structure is used to store the join predicates.
How can we find the join predicates applied on a relation from relid, Oid or RangeTblEntry ?
I want to construct a join graph for a given query, for which I need the join predicates between two relations.
