Re: Support NOT VALID / VALIDATE constraint options for named NOT NULL constraints

[jian he]

hi.
in notnull-notvalid.patch

+ if (coninfo->contype == 'c')
+ keyword = "CHECK CONSTRAINT";
+ else
+ keyword = "INVALID NOT NULL CONSTRAINT";

we have a new TocEntry->desc kind.
so the following related code within src/bin/pg_dump also needs change
----------------

                                if (strcmp(te->desc, "CONSTRAINT") == 0 ||
                                    strcmp(te->desc, "CHECK CONSTRAINT") == 0 ||
                                    strcmp(te->desc, "FK CONSTRAINT") == 0)
                                    strcpy(buffer, "DROP CONSTRAINT");
                                else
                                    snprintf(buffer, sizeof(buffer), "DROP %s",
                                             te->desc);

            else if (strcmp(te->desc, "CONSTRAINT") == 0 ||
                     strcmp(te->desc, "CHECK CONSTRAINT") == 0 ||
                     strcmp(te->desc, "FK CONSTRAINT") == 0 ||
                     strcmp(te->desc, "INDEX") == 0 ||

                     strcmp(te->desc, "TRIGGER") == 0)
                te->section = SECTION_POST_DATA;
