Add code to extract dependencies from an expression tree, and use it
Tom Lane <tgl@sss.pgh.pa.us>
Add code to extract dependencies from an expression tree, and use it to build dependencies for rules, constraint expressions, and default expressions. Repair some problems in the original design of recursiveDeletion() exposed by more complex dependency sets. Fix regression tests that were deleting things in illegal sequences.
