Reimplement parsing and storage of default expressions and constraint expressions in CREATE TABLE. There is no longer an emasculated expression syntax for these things; it's full a_expr for constraints, and b_expr for defaults (unfortunately the fact that NOT NULL is a part of the column constraint syntax causes a shift/reduce conflict if you try a_expr. Oh well --- at least parenthesized boolean expressions work now). Also, stored expression for a column default is not pre-coerced to the column type; we rely on transformInsertStatement to do that when the default is actually used. This means "f1 datetime default 'now'" behaves the way people usually expect it to. BTW, all the support code is now there to implement ALTER TABLE ADD CONSTRAINT and ALTER TABLE ADD COLUMN with a default value. I didn't actually teach ALTER TABLE to call it, but it wouldn't be much work.

extern Relation heap_create(char *relname, TupleDesc att,
Make it possible to execute crashed CREATE/DROP commands again. Now indexes of pg_class and pg_type are unique indexes and guarantee the uniqueness of correponding attributes. heap_create() was changed to take another boolean parameter which allows to postpone the creation of disk file. The name of rd_nonameunlinked was changed to rd_unlinked. It is used generally(not only for noname relations) now. Requires initdb.

Hello. The following patch extends the COMMENT ON functionality to the rest of the database objects beyond just tables, columns, and views. The grammer of the COMMENT ON statement now looks like: COMMENT ON [ [ DATABASE | INDEX | RULE | SEQUENCE | TABLE | TYPE | VIEW ] <objname> | COLUMN <relation>.<attribute> | AGGREGATE <aggname> <aggtype> | FUNCTION <funcname> (arg1, arg2, ...) | OPERATOR <op> (leftoperand_typ rightoperand_typ) | TRIGGER <triggername> ON relname> Mike Mascari (mascarim@yahoo.com)
