From 7c6df91dda27accab3097390ef0d21d93028c7a1 Mon Sep 17 00:00:00 2001

Subject: Second phase of committing Rod Taylor's pg_depend/pg_constraint
 patch. pg_relcheck is gone; CHECK, UNIQUE, PRIMARY KEY, and FOREIGN KEY
 constraints all have real live entries in pg_constraint.  pg_depend exists,
 and RESTRICT/CASCADE options work on most kinds of DROP; however, pg_depend
 is not yet very well populated with dependencies. (Most of the ones that are
 present at this point just replace formerly hardwired associations, such as
 the implicit drop of a relation's pg_type entry when the relation is
 dropped.)  Need to add more logic to create dependency entries, improve
 pg_dump to dump constraints in place of indexes and triggers, and add some
 regression tests.
