Hi,
I (a graduate student) am currently trying to modify a postgres instance slightly to incorporate my modified cardinality estimates. In order to run these experiments I'm hoping to access the raw values for selections predicates from within the calc_joinrel_size_estimate method (in costsize.c). For example, if the restriction
WHERE name_attr = "example_str"
appears in the query, I'd like to get the "name_attr" and "example_str" values. If possible, I would very much appreciate the help.
Best, Walter
