Tom Lane	845a6c3acc	Code review for domain-constraints patch. Use a new ConstraintTest node ... type for runtime constraint checks, instead of misusing the parse-time Constraint node for the purpose. Fix some damage introduced into type coercion logic; in particular ensure that a coerced expression tree will read out the correct result type when inspected (patch had broken some RelabelType cases). Enforce domain NOT NULL constraints against columns that are omitted from an INSERT.	2002-08-31 22:10:48 +00:00

Tom Lane	7c6df91dda	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.	2002-07-12 18:43:19 +00:00
Bruce Momjian	1666970275	I've fixed up the way domain constraints (not null and type length) ... are managed as per request. Moved from merging with table attributes to applying themselves during coerce_type() and coerce_type_typmod. Regression tests altered to test the cast() scenarios.
