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
