Re: NOT ENFORCED constraint feature

hi. some minor issue about v7-0001.

there are 5 appearances of "sizeof(CookedConstraint)"
to make it safe, it would be nice to manual do
`
cooked->is_enforced = true;
`
for other kinds of constraints.

static bool
MergeWithExistingConstraint(Relation rel, const char *ccname, Node *expr,
bool allow_merge, bool is_local,
+ bool is_enforced,
bool is_initially_valid,
bool is_no_inherit)
{

- if (is_initially_valid && !con->convalidated)
+ if (is_initially_valid && con->conenforced && !con->convalidated)
ereport(ERROR,
(errcode(ERRCODE_INVALID_OBJECT_DEFINITION),
errmsg("constraint \"%s\" conflicts with NOT VALID constraint on
relation \"%s\"",
ccname, RelationGetRelationName(rel))));

There are no tests for this change. I think this change is not necessary.

there should be
ERROR: cannot validate NOT ENFORCED constraint
?

Do we need to update create_foreign_table.sgml
and alter_foreign_table.sgml?
